TwoTone - Put all your emotion app for iPhone and iPad

Is there anyway I can put feeling into a picture I felt?

FillTone can express warmth, coldness, and freshness with colors of light.

From where did FillTone get inspired?

“If the sunlight you saw is purple, then draw with purple.
If the sea is red, then draw with red.”
- Monet -

Motivated by this so FillTone came out.
