Once I started watercolor painting I saw or at least noticed more colors than previously. I also started to describe them, at least to myself, by tube names. The sky became a thin wash of ultramarine shifting gradually to cerulean until, near the horizon, it was overlaid with a wash of lemon yellow (one of the only descriptive names) so that there was a touch of almost green as the sunset started.

Sadly it seldom looked like that on the paper. sigh
