Looks great! I really like the RGBA overlay. Not sure about the massive preview circle while selecting (a bit big and difficult to discern where the selected colour is), but I’m sure I’ll get used to it quickly.
A few gestures on the floating colours could be useful though, such as:
- Dragging the colour onto the canvas to quickly select a colour (eyedropper).
- Dragging the fill on top of stroke (or vice-versa) to swap the fill and stroke.
- Double-tap to toggle the colour on or off.
Short hex colours still don’t work though.
