I've had time out recently, time to think and here's my thought to occupy you over the holidays. Why are there only three primary colours? Who decided that we should be restricted to this number. I mean BLUE, RED and YELLOW have been around for some time and I should have thought that someone would have found another by now. Just trying to imagine another colour that could not be manufactured by mixing any of the existing pigments excluding white hurts after a while. To be sure the three we have are pretty adequate but just imagine the scope we would have if there was suddenly another one. What would that colour look like? What colours we could mix with it!! I'm sure that somewhere on this planet there must be a mineral or a chemical of a totally different colour than anything we know of. We would have to re learn colour theory and obviously colour mixing would be all together different. I'm now going to continue thinking, after I've had another Whisky! Merry Christmas everyone!
