Colors palette origin pointer & modification
When import Sketch layout, you can see generated colors but it doesn't tell you where it get that color from.
For example I got two particularly similar colors from this one file
I have no idea where I should be using it.
Perhaps showing a magnifier around the origin of that color or hilight that colors when hover is an idea.
While testing a bit, I see some unnecessary colors getting picked up (these are from dummy artwork). Designer should be able to remove this from palette.
When importing PNG file, colors generation doesnt work. We should have an option to pick the color ourself. This would also allow fine tuning for those needed as well.
I love the way colors name got generated for you, feels great. If possible perhaps colors suggestion might be a good idea. For instance, when importing a new screen there are three new colors. These colors should get push to the top (or its own section) to show there are new colors picking up. You could go so far as suggesting correction if very similar color is already in the Guideline.
My today theme is color :D Loving it a lot so far, really look forward to see how this grow.
