The Wheel of Color
Last week I had the pleasure of teaching a color mixing program for adults at a local library. The “mixed” results were wonderful, and it was thrilling to see the participants get creative with color and the color wheel.
We talked about the vocabulary of color, and I offered the students an overview of some of the most common color terms. Color is a very complex subject, and could be the subject of study over many lifetimes, so I tried to keep it simple and clear, yet informative.
One of the most important terms is Hue: The “color of a color”. Hue is what we usually mean when we ask “what color is that?“ Hue is the term for the pure spectrum colors commonly referred to by the color names, such as red, yellow and blue. Different hues are caused by different wavelengths of light. But the relationship of light and color (color is actually an “effect” of light) is a subject for a different post!
I also touched upon Chromaticity. This property of color tells us how pure a hue is. That means there is no white, black, or gray in a color that has high Chroma. Often referred to as “colorfulness,” Chroma is the amount of identifiable hue in a color. A color without hue is achromatic or monochromatic and will look gray.
As the students moved around and through the color wheel mixing colors, they discovered how the purity of a hue effected what could be mixed from it. Some reds are a bit closer to blue, and some to orange. Some blues are closer to purple, and others to green. This effects the hue of the secondary colors can be mixed from these primary colors. Thus color mixing can become a real adventure, a challenge, stupendous fun, and always a voyage of discovery.
Students experienced “saturation” of the colors they worked with. Saturation, also known as “Intensity”, describes the strength of a color. Related to chromaticity, saturation tells us how a color looks under certain lighting conditions. A room painted a solid color will look different at night than in daylight.Think about Saturation in terms of pale or weak and pure or strong, NOT light or dark. The terms Purity, Intensity, Saturation and Chroma are often used interchangeably when discussing color.

When mixing colors, hues can be desaturated (reduced in purity or weakened), in one of three ways: mixed with white to lighten the value (creating a tint), mixed with black to darken the value (shade), or mixed with gray or the complement to either lighten or darken the value ( tone).

Students were given the three Primary Colors: (Paint colors) Red, Blue, Yellow to work with. These are the colors which cannot be mixed or created through combining other colors.

They created Secondary Colors, which are mixtures of each two of the primary colors: Purple (blue + red), Orange, (yellow + red), Green (yellow + blue).

We also explored Tertiary Colors which are mixtures of a primary and secondary color next to each other on the color wheel, and contain the names of those colors in their names! The Tertiary Colors are: yellow-green, yellow- orange, red-orange, red-violet, blue-green, and blue-violet. (For our purposes, we are using purple and violet interchangeably).
Students also learned about Value, or the lightness or darkness of a color. When we describe a color as “light” or “dark”, we are discussing its value . The property of Value tells us how light or dark a color is, based on how close it is to white. For instance, yellow would be considered lighter than navy blue which in turn is lighter than black. The value of a color is also is also related its brightness.

One of the most endlessly fascinating color relationships is that of Complementary Colors, which are color pairs opposite or across from each other on the color wheel. Combining complimentary colors can produce “neutral” browns and grays, as their combination effectively “cancels out” the color properties of Hue, Value and Saturation. The complimentary pairs are made up of one primary and one secondary color, which are directly opposite each other on the color wheel: blue and orange, yellow and purple, and red and green are compliments.
Above we see how the complimentary pair red and green, as well as blue and orange help this artist to reveal another face of color.
Color is science, but it is also emotional, expressive, and FUN! Find some paints, and start your color exploration… investigate, experiment, explore and experience the power of color to change your state of mind, or even how warm or cold you feel. We can actually FEEL a difference of 7 degrees in temperature, depending on what colors we see and are surrounded by. Such is the power of color. Color is powerful, but don’t forget to play with it, too!
