Tone

Kazimir Malevich - Prayer - http://www.wikiart.org/en/kazimir-malevich/prayer-1907

This design uses a great deal of tone for it to work as a piece of art. The colour used if was just one flat colour it wouldn't work and have a great deal of depth without having no tone in it. I like the fact it's orange it is very different yet stands out and works well.
