Don't add the same color to color history twice

[ghost]

Color history should not show the same color twice. Otherwise, the user might lose other colors saved in history if he or she selects the same color twice by accident.

(this is not very useful)

Thanks for the great idea! I would like to implement it like this:

• if a non-existent color had been picked, the left-most color is kicked out and the new one is added to the right (like the way it's implemented now)
• if a already existent color had been picked, the color just get selected (like you would click on it in the color history) Would love to hear your opinion!

Yep. thats exactly what I had in mind.
