How are there colors?
we can see colours only because the objects we see reflect part of the visible spectrum. White light is made up of red, orange, yellow, green, blue and violet light. We can see objects as different colours because they absorb and reflect parts of this visible light. For example, an object that is red appears red because it reflects the red part of the spectrum and absorbs the other colours.

The secondary colors are colors that can be made from the 3 primary colors- red, yellow, blue. The 3 secondary colors are- Green (yellow and blue), Purple (red and Blue), and orange (red and yellow). Those colors and primary colors make intermediate colors like yellow orange and blue green. In intermediate colors you must always state the primary color first.
