When used correctly, color can change the mood of the image, or impact the story. It can also draw the viewers eyes to a focal element. In the image below, digital colors are used effectively to focus your attention on the tube. And the controlled color palette also helps keep the image calm.

Saturation and Value

A lot of people think Colors are all about harmonious relationships. But Saturation and Value are equally as important, if not more so. Without a clear understand of what saturation and value is, and why it’s important, no color scheme will ever help you. Saturation is about intensity, and Value about Brightness/Darkness.

At 20% saturation, red turns into a fleshy pink.

And at 20% value, red becomes a dark muddy brown. In fact just using the color red as a starting point, you can create these shades simply by changing the saturation and value:

“Yeah, but why is this important?” Because Saturation and Value can make or break your image. The biggest problem I see with CG renders is oversaturation:

Example of an overly saturated scene

By forcing strong saturated colors on the viewer, you give them no where for their eyes to rest. Just like you never go full retard, you should never go full saturation. Here’s a much better level:

Corrected scene

Not to say that saturation is bad though. In fact it can be excellent when used in moderation:

Maxfield Parrish – Salzkarawane am toten meer (from ArtRenewal.org)

The striking red mountains catch your eye immediately. Doing so makes it the focal element of the entire image. In this image, a single note of saturation helps to guide your eyes through the scene:

Giuseppe de Nittis – The place de carrousel and the ruins of the tuileries palace in 1882 (from ArtRenewal.org)

And in this image, saturation is used to make Jesus look powerful amongst a group desaturated onlookers.

Saturation can even alter your mood. At the start of Pixar’s UP, the colors are vibrant and alive to signify their joyous life. But when tragedy strikes, the colors are immediately desaturated.

This simple touch of desaturation makes the viewer feel the pain and loneliness of the characters. It’s used extensively in hollywood and first-person shooters. For cartoons, saturated bright colors can play to the artists advantage, as it immediately tells the viewer that this is fake:

So as you can see, learning how to use Saturation and Value effectively can vastly help tell your story. With that out of the way, we can finally get into…

Color Harmonies (aka Color Schemes)

Everyone knows that some colors look better together than others, but it can get confusing if you try to remember which ones. Here are 6 of the most effective Color Harmonies…

1. Monochromatic

This one is the easiest to remember, because it’s just one color. Due to the absence of other colors, the viewer is left to focus on the differing values and saturation. Making it great for single subject shots or dramatic atmospheric scenes.

Examples:

Hermann David S. Corrodi – The ambush (from ArtRenewal.org)

Check out more monochromatic examples here.

2. Analogous

Analogous harmonies use colors that are adjacent to each other on the color wheel. It’s frequently seen in nature, making it great for creating a calm, comfortable and peaceful mood.

Examples:

3. Triadic

This one is probably one of the hardest to pull off well. It’s three colors that are equally distant to each other. It’s hard to do, because if used in equal amounts it can create ugly chaos. It’s best used for cartoon style scenes since the colors can look almost childish.

4. Complimentary

This one is definitely the most popular: colors on opposing sides of the wheel. They just naturally go well together. A common misconception is to use equal amounts of each, but this will more than likely create ugliness. You want to choose one color as the predominant one (usually the cooler color) and use the other to create splashes of interest. Use lots of browns and greys for a better effect. Examples:

Complementary colors accentuate each other. Meaning that a dull green against a red background, will suddenly look more saturated. So be careful of the saturation.

5. Split Complimentary

Similar to the complimentary harmony, this involves taking one opposite color and splitting it. This is useful for extending your palette (when two colors aren’t enough), or to create a more joyous mood. Examples:

6. Double complimentary

Just like the complimentary harmony, only double. Two pairs of complimentary colors (doesn’t matter where on the wheel). You have to be careful with this one as using equal amounts of all four will create chaos. It looks best when the foreground is one pair, and the background is another. Mixing the pairs can get tricky. Examples:

Thomas Moran – The autumnal woods (under the trees) from ArtRenewal.org

^Notice the complimentary pair of colors in the foreground, and another in the back?
