Purple is a good color, but I think it's underused in art. Almost all painters, I think, and this is my interpretation, are experimenting so much that they're trying to use fewer colors, fewer combinations. I wouldn't like to see the paintings invisible. Like the fable of the king in his invisible suit. We have hundreds of incredible color combinations. Why not use them? Well, no one has the absolute truth about anything, least of all art. You can die peacefully and your paintings will be worth a lot, five centuries later.
