The Three Dimensions of Color
There are three different and measurable characteristics of every color what are known as the “Three Dimensions of Color.”
This is the most obvious dimension; it identifies a color by its name, i.e. Red, Blue, Green, Yellow, etc. Every color falls into a definite hue category. So if someone say’s what hue is it, you would look at the color and identify it and that would be the hue.
Value, locates the color’s approximate position in relation to white and black. It is the lightness and the darkness of a color. We need to understand this because if you have no understanding of “value” your paintings may not ever look right. By adding white to a color you have changed the “Value” but the Hue remains the same. When we add black to a hue we get a “shade” of that color, we still have not changed the “hue” only darkened the value.
This is also known as Chroma, simply put this means the “purity” or “strength” of a color. Colors are brighter in their pure state than when mixed with any other color or grey. You can change the intensity of a color by adding white or black or its complimentary color. Doing this makes them less intense. For example, if you add a touch of purple to yellow the color is weakened because you reduced its intensity
