So, I was thinking; with the smudge tool added, there's a lot more shading in PT. However, it's hard to shade with multiple colours. I thought "wouldn't it be nice if there was a tool to change the colour, but not the shade (how light/dark it is)?" It would save a lot of artists time, and make it easier to turn a well-shaded ball into a colourful well-shaded ball. Feedback?
