Often people believe they need a white in their paint palette, but with watercolours this isn't true. The white of the paper is all you need to build your highlights first.

Inspired byy the blue sheen on a seagulls white feathers, this very light, delicate, transparent blue is the "barely there" touch that you need to take your painting to the next level.
