First choice of colour

blue.............blue is beautiful, blue is best, Im blue, Im beautiful Im best.
blue (ultramarine) was also the colour which was the most expensive pigment in oil paintings of great antiquity, so I wasnt just being spaced out.

H aha
just saw this,a 'Dougal and the Blue Cat' quote FTW.

Also its Lapis Lazuli (ground up precious stone) which was the most expensive pigment, ultramarine is a 'modern' chemical version of the same colour.
