I confess to have never been attracted by using a limited palette in a painting. When there are so many wonderful colours on offer, I couldn't see the point of restricting yourself to one, two or just three.
However, having now done a 'greens only' challenge and more recently a 'blues only' challenge I have had a revelation - using a limited palette is easier (or at least I have found it so). It removes all those difficult decisions about combining colours, finding complementary colours, colour triads, etc - all things that have me scratching my head.
Using the blue on my latest one of the pierrot was much less cerebrally challenging than trying to paint the portrait using all my normal colours. No choices - just put your brush in some blue paint - job done.
It has certainly got me thinking now - perhaps I might try to use fewer colours in my paintings, both in an effort to produce more cohesive work and also to retain some of my sanity as colour combining and deciding on a complicated palette has routinely seen me tearing my hair out.
Ain't learning a wonderful thing!
