This is going to be a pretty small post - just a musing. Been working with photoshop a lot lately, and I've noticed something. The range of colours that lie between purples and cyans is defined as blue. The range of colours that lie between yellow and cyans are defined as green. Both of these ranges are fairly large. However, when it comes to Red, the range is very small. A little one way and you get pinks. A little the other way, and you get oranges. Same with Yellow - a very small range of colours is yellow. I'm talking only about these four colours because RBY are the three primary colours, and RGB is a popular method of colour representation.
