[Aquanet] orphans in the palette

[Patrick Davis]

Hi, gang.

Getting back at painting after a long layoff causes me to examine what I 
am doing... and with what. Looking at my palette, I realize there are 
certain colours I never or almost never use. Most notable for me are two 
blues, cerulean and cobalt, the former neglected because it is chalky 
and the latter because to me it seems gutless. I'm sure some of you do 
use these, so maybe you'd share with me what you use them for?

Another orphan is dio purple, but it is shunned for the opposite reason: 
it does not play well with others.

Any comments on these?

cheers
