Hue: “Colour” is a general term which people use to name all the hues, tints, and tones. On the other hand, a hue is exactly the thing we mean asking “what colour is it?”. Basically, it is a family of twelve pure and bold colours presented on the colour wheel.
Secondary Colours/Hues: Secondary hues can each be produced by mixing two primary hues. These are orange, violet and green.

Saturation: Chroma, more often called saturation, refers to the intensity and purity of a hue. A hue will be most vivid in its natural state at 100% saturation. At 0% you will have the monochrome luna component.
Contrast: The complementary scheme is the mix of colours placed in front of each other on the colour wheel.
