Hue, Value, Saturation.
When you have to identify a color you have to follow these 3 rules.
Hue: When your painting something, the first thing you have to do is identify what hue it is i.e. when your painting something green, you have to first identify what kind of green it is, is it a blue-green or a yellow green.
Value means how light or dark the color is.
Saturation means how pure the color is. Very often you will not use pure bright colors, you will have to reduce the saturation or intensity by adding greys.
It can be a little frustrating in the beginning when you first go to an art store to buy paints, there are hundreds to choose from. Basically all you need to keep in mind is there are only two kinds of each color, a warmer version and a cooler version i.e. there are only two kinds of red, a warmer orangish red and a cooler violetish red.
Then there is also saturation that is the purity of a color and value how light or dark the color is. cadmium yellow is a pure bright yellow whereas burnt umber is a desaturated and very dark yellow
