Anyway, for some reason I thought I'd try a grey background for a change. After applying it I got my cloth and 'drew' the clouds in the wet grey paint. At this point the painting looked like this:
And now it looks like this:
|Sun in the Water, 33.5 x 59", oils on panel|
I really liked the experience. The grey ground immediately unifies everything you do on top of it. The down side (like fellow-painter Dave Smith pointed out) is that your colors may not turn out as bright as with a white background. I wouldn't use it for a sunny beach scene. It's probably best suited for paintings with a soft atmosphere, like this one. I will certainly use it more often!
