Color dialog not fully working

[PaulBol]

I noticed that the color dialog is not working properly as shown in this screenshot.

• The column with shades on the right should update to the selected color, if I remember correctly
• Entering numeric values has no effect (e.g. red=green=0, blue=255 should show blue)

I don't really need the control and maybe instead of fixing the Mono dialog an implementation based on NSColorWell is a better approach. Just wanted to make sure to record the issue for now.

It's possible that some of the text box events are not properly fired causing the color not being updated.

Using NSColorWell would be better approach for the color dialog overall.
