Here I wanted to create the sky dark, this time letting the rainbow sing louder.
The compo of sky quickly shifts, twists and turns, it's good to be decisive standing there, choosing an effect of a moment and trying to work this out fast.
Of course one must pay attention to the light effects surrounding this rainbow as well, in this case, the beach is dark, in shade and the ocean gets lit partly.
Fun to paint!
And a clear blue sky after
