Who produced this arbitrary idea and called them ‘primaries’?ģ. There has been no rule really that only three colours should mix all other hues in the world.
So, it does look like an overwhelming part of the colour wheel focuses on those hues. Human eye can see more variation in the yellow-orange section, and more pigments have been discovered/ invented in the same. The colour wheel itself is limited by the following facts:ġ. While I debunk the RYB colour wheel and wax lyrical about the CMY one, keep in mind, this is simply what has worked with the available pigments we have in watercolour. You can learn a bit about the wheel and use it as a shortcut to help you make quicker painting and paint mixing decisions. But can it be helpful? I choose to think YES! Honestly- NO! It is just one way envisioned by humankind to explain the intersection of colour properties and our vision and simplify things. So- does the colour wheel really represent the true be-all and end-all of colour theory? It really is a demonstration of additive colour mixing, but taking this idea to painting, with ‘primary’ colours on a wheel, that too placed geometrically at the places of 12, 4 and 8 on a clock, is purely a man-made invention. Spinning this disc with the visible spectrum, would imprint those colours on the eye in a rapid motion, mixing optically and produce…. He used this to demonstrate additive mixing by spinning this as a disc- also called Newton’s colour disc.
