CMYK Colour Wheel

The CMYK Colour wheel is the proper for artists and designers that can be understood by looking at additive and subtractive colour systems. Additive is colour created by light for example computer and television screens (RGB) when the colours start to mix they begin making lighter colours and when red green and blue are all blended they create white, but when using something like paints when mixing the colours it turns into a muddy mess of colours and not white which is where subtractive colour comes into it. Subtractive colour is Cyan, Magenta and Yellow when you mix these colours you get red, green and blue and then when they are all combined you get black. So this is why the CMYK colour wheel is the proper one, with cyan, magenta and yellow being primary colours and red, green and blue being secondary colours.
