When selecting colors, it's hard to remember what color is the "fill" and which one is the "outline" one.

There's already a distinction that the outline color is at the top left corner while the fill color is at the bottom right corner. And in my opinion, area which represent color should appear completely filled for better visibility.

Or what about tooltips like GIMP 👇🏽👇🏽👇🏽

It already does show tooltip on Outline Color and Fill Color

Yes, yes, but... my point is that it is not undoubtedly easy to see them at a first sight. You have to either have learned their positions, check the preview to their right, read the tooltips or just try it and check...

With a simple visual helper it would be impossible to fail, no matter if you are newbie, a pro coming from another software or a Synfig guru with a bad day, hehehe.

Anyway, it is just an UX-UI suggestion, if you all feel like it is fine as it is just forgive me =)

Cheers
