Great idea with the defaults! I've just tried it out on Linux. It does seem to remember my last choice and offers me some defaults. But somehow the window look off:

The defaults are hard to see and the rectangle saying "Preview" to the left is strange. It also says "Color Name: #ffffff" even though it chooses the last selected one correctly when pressing "OK".
