The Need for Light and Dark

 

I planned on talking about color variation this week but then it occurred to me, that we will need to talk about color contrast and you can’t talk about contrasting color without talking about value. So, I switched up my plans and we’re going to talk about the often neglected concept of color’s lights and darks, otherwise known as value.

The Light and Dark of It

So, what exactly is value? Value is simply what I just mentioned – the lightness or darkness of a color. This has nothing to do with their hue. Remember, hue works more like a category so mint green and hunter green both are a green hue, but mint has a light color value while hunter green has a very dark value.

The most important thing to remember about value is that it used to create contrast. For instance, purple has a much darker value than yellow, right? Used together, they are high in value contrast and, so, make a rather dramatic color palette. On the other hand, a dark magenta and forest green will have the same or similar middle-dark value. Putting them together will not create much value contrast. Although there is nothing wrong with that – they belong to complementary (opposite) hues on the CMY color wheel so they have contrast there – the lack of value contrast greatly reduces the potential of their dramatic contrast in hues.

To be blunt, similar values in rich colors such as dark magenta and forest green would just be boring. Now, if you choose a slightly darker magenta and a lighter green such as a burgundy and an jade, that will increase the value contrast and make a much more interesting color combination, as seen in the example image here. Below the color combinations you see them with the hue removed, leaving just their gray value. So that’s another way you can think about value – it’s the lightness or the darkness of the color without any color in it.

 

Seeing the Value

If you are a painter you might be shaking your head at the simplicity of the above explanation so let’s get a bit more precise. (If your head is already spinning a bit, just read through this but don’t worry about understanding it fully yet. You can come back to this later.)

Value is not just the lightness or darkness of a color. It is the lightness or darkness of what is SEEN. That’s an important distinction because the color of things we are looking at out in the world won’t stay constant as the light changes.

For instance, have you ever been around someone in a restaurant or on a train – some poorly lighted space – thinking their hair is dark brown only to see them step outside and find that it’s a rich red? Their hair didn’t change color. The light did.

The less light there is, the darker things appear, right? That seems obvious, but it’s really important to consciously understand that. It underlines one of the primary principles about creating art, especially imagery you’re trying to reproduce in any realistic manner – it’s not about what you think something is, it’s about what you actually see. So, if you are painting a portrait of me in a dark room, you would not paint me with the bright henna red and copper hair you know I have, because in the dim light, my hair would not actually look red or copper.

You may not be a painter but if you plan to build images in canes or are painting with polymer or create pretty much anything where you are developing a two-dimensional illusion of form and depth , you will be working with these kinds of value changes in color. Even if you don’t create imagery, the concept of how light changes the value of a color is useful for understanding what value is and why it is important in your designs.

You’ve actually learned about the importance of value if you’ve ever tried to draw a ball – to make it look round you have a very light spot where light hits the sphere directly, a dark side where the light doesn’t reach, and a gradation from light to dark between the two. Now, if that ball had color, like the blue ball you see here, you can tell that it’s a solid blue ball even though it actually has a variety of blues in this rendering of it. But I couldn’t just fill in a circle with one shade of blue and have you understand it is a ball. We need to see that change in color value – the swatches pulled from the blue ball are all the same hue of blue but are all different values – in order to see a dimensional form.

Without those changes of value – those lights and darks, those highlights and shadows – everything would just look flat. That is also why you don’t want to take a photo of an object with the light shining directly on the front facing view – it will kill the shadows, eliminate value changes, and make it difficult to perceive its form.

 

Intentional Value

So, a change in color value provides us with visual information, right? We like that. We like to be able to perceive if something is round or flat, textured or smooth. The contrast between light and shadow gives us that information. It is one of the reasons that we look for (mostly unconsciously) the contrast in value in works of art as well. Contrast, or the lack of it, can tell us a great deal.

In these beads by Jennifer Morris, there is very little contrast in value but these are not about drama so it makes sense. There are muted and pale colors with feminine floral motifs on round forms with low value contrast to match. The intention for this to be soft and quiet is obvious and with all the characteristics servicing that intention, she has designed some very lovely beads.

On the other hand, here are liquid polymer painted pieces by Lynn Yuhr who is clearly going for a bold and graphic look with wide ranging color values to support that objective.

So, don’t think that you must have a high contrast in the value of your colors. It can be high or low depending on what will best serve your intention. Value contrast also can bring attention to certain portions of your work or lead your eye around the piece.

For example, the fish on this clock by Gera Scott Chandler are much lighter in value than the background, bringing our focus to them first. The light value of the circles on the background subtly connect to the larger fish since they are similar in value so that your eye moves from fish to circles, going around the face of the clock.

 

Furthering Your Color Consciousness

So, before I get into how to manipulate values – something we will get into next week – I suggest you spend some time getting familiar with the values of color. I have a couple suggestions for you.

Go Grayscale

To better familiarize yourself with the actual value of colors, I find it helpful to look at colors in grayscale. A grayscale image will show you the actual value of colors, relative to the colors they are grouped with.

This means taking photos of your work in “black and white” mode or changing color images (yours or other people’s if you want) to grayscale in a photo editing app or software. Not all cameras have a black and white (or grayscale) mode. If you’re not sure, look up your camera model online along with “how to shoot black and white” and if no information comes up, then it probably doesn’t have that option.

The other way to do this is to edit the image. To do this on your computer, use Photoshop or whatever default photo editing software is available on your computer.

• In standard Photoshop, go to Image> Mode> Grayscale.
• In Microsoft Paint.net, you go to Adjustments> Black and White.
• If you are using another program, search the web for “how to convert image to grayscale” along with the name of your editing program.*

If you take a picture with a mobile device, you can usually edit it to grayscale directly in the phone or tablet.

• On an iPhone or iPad, select an image, hit “Edit”, tap the three overlapping circles icon, then scroll the little thumbnails of the photo over until it is in “mono”. Tap “Done” if you want to save it but keep in mind it will save over the original. If you do this accidentally, just follow the same steps and you’ll find the original version in that little row of thumbnails so you can convert it back.
• In Android, and pretty much any mobile device, you can use Google photos. Open your image in this app, tap it to bring up the icons and choose the three stacked lines. Slide the thumbnails over until it is in “Vogue” mode. You can also save it and undo it later.

*Note: There are quite a number of articles online suggesting you convert an image to grayscale by using a “saturation” adjustment. DO NOT do that for this value exercise. As we will discuss next week, saturation has nothing to do with color value. Reducing saturation tends to also reduce value, more for some colors than others. It will completely mess you up. You need a conversion to “grayscale”, “black and white”, or “mono”.

If using software and apps is just too much of a bother or you don’t have a software program, here is a free online service. You just click the file icon, browse to and open the file, and it will appear in the browser window in grayscale. You can save it from there by hitting the floppy disk icon.

Once you have these grayscale images, start looking at how much value contrast shows in the images.

• Is there a lot of contrast or all the values fairly close?
• Does the amount of value contrast match with the probable intention or feel of the piece?
• Do any of the colors set next to each other just blend into one another because the values are so close? If so, do you think that works for the piece or do you think more value contrast could help it? (We’ll talk more next week about how to choose alterantives when you want a different value.)

Just make yourself more familiar with value. You can also use this value scale (click on it, then print it out) to check values of colors or pieces you have. You can lay the scale next to a color and see which value you think is the closest. Then take a photo of the scale next to the color, convert it to grayscale, and see how close you came to matching the color to the right  value. Do this a few times and you’ll be seeing in values quite quickly!

 

Get a CMY Color Wheel

You know how I recommended you get a CMY color wheel? Well, the more I work on these articles, the more I wish you ALL had the CMY color wheel from the Color Wheel company. I can’t tell you how many times I reference mine, and I am convinced that when we get into how to use these color concepts to pick color palettes and to mix color, having this particular CMY color wheel will make it all such a breeze.

No, they’re not paying me to push this. I have met the owners and they are a fantastic little family company (who worked with the polymer community’s very own Maggie Maggio to help build a CMY based grade school art curriculum, by the way) but more than that, they are so intensely passionate about color and education. That’s why they’ve done such a superior job with this particular color wheel.

So, if you haven’t gotten one yet, you can buy it directly from the company for $9 (including shipping in the US) and you will have it within 5-7 business days. It’ll be the best $9 you ever invested for your creative journey. Outside the US, I am not sure where it is best to get them but you can search for “Color Wheel Co CMY” and look for this wheel:

Well, I hope you’ve enjoyed this immersive in value. I have to say I am always surprised at how much there is to talk about each characteristic of color. These articles really could be much shorter but I don’t know if you would walk away really understanding and feeling confident about these concepts. We retain concepts better when we spend some time with them. I’m hoping these articles do that for you! If you have any thoughts or suggestions about the length or detail of these articles, I am always up for hearing them. Just reply to this if you get it by email or write me through the website. 

 

Wondering about my references to Intention? Or how to support this content?

Read what so many VAB members have said was a life altering (or game changing or mind opening) set of articles on Intention in the February edition of the Virtual Art Box and catch up on the concept of marks, lines, and shape too. And they are all on SALE, 25% off right now – no promo code needed. I’m also having a 20% off sale on ALL books!

The purchase of a box would help support this free content that I am creating now as well as give you a stronger base for the conversations we will be having going forward. You can help me keep the lights on by making a purchase of any of the publications I have on the Tenth Muse Arts website or by making a one-time or monthly contribution here.

Thank you for your past, present, and future support!
