If two of the primary colors are mixed together, a secondary colour is created. As more colors are mixed, the selection of colors grows.
Additive Secondary Colours

Secondary additive colours are produced by mixing two additive primary colours together.
The additive primary colours are Red, Green, and Blue. Mixing these produces three secondary colours:
- Cyan
- Magenta
- Yellow
If these secondary colours are mixed further, they produce what are called tertiary colours.
We use subtractive primary colours when mixing paints or inks. In printing, the colours used are Cyan, Magenta, Yellow, and Black (CMYK).
Subtractive Secondary Colours

Secondary subtractive colours are produced by mixing two subtractive primary colours together.
The subtractive primary colours are Red, Blue, and Yellow. Mixing these produces three secondary colours:
- Violet/Purple

- Green
If these secondary colours are mixed further, they produce what are called tertiary colours.
