Black Beauty.

Talking with a friend about potencial of black color in paper decoration, I decided to experiment the effects of contrasting black - white. Then, I prepared a black paste and went to paint my white papers. Finally with some combs I removed the paint to evidence the whiteness under. The effect is really amazing, it's like the paint moves while you see it with attention. This is the classical effect of optical visions. Here are some of the papers I've done.
