Just when you thought you'd finished with iColorama...

along comes a stunning new upgrade, providing lots of artist's brushes.

Brush/artist. This is a sample of the 27 brushes found under the brush image at bottom left of the screen. 
Eight sliders, including size and colour jitter - and this is just the first installment, there are another 24 brushes if you tap the brush pot symbol. 

A grea app just got even better.
