The Invertible by wraifen
A sort of side project of mine. The course of this drawing was altered rather dramatically when somehow, whilst I was experimenting with irreversible color changes, Adobe saved over the original.
Whether this was a "happy little mistake" or not, well, I'll probably never know.
Upon further color experimentation I discovered that this painting was very much "Invertible." And what I mean by that, is, that when you invert the colors, the result is something that doesn't appear to be inverted at all.
