For reference this is about the Path2D beta
I feel like a powerful feature that could be added to this is the option for per-control point colouring for Path2D.
The use case, what I need this for personally, is a colour wheel:
When you adjust the saturation it would be a nice detail to have it so the outer ring (which represents the hue) desaturates and saturates depending on the selected saturation. This of course isn’t possible using image labels – which is what I’m using currently – because we have no option for non-linear gradients.
Path2D would be an excellent candidate for this because I could simply create a circular spline made up of differently coloured control points, then interpolate the colour of each control point as needed instead of relying on an image label which of course has no option for saturation/desaturation.
