The Undo and Redo tools for Color Picker feature have been fixed!
You can now see the correct color history of your elements based on previously selected colors by clicking the Undo tool. Likewise, ticking the Redo tool will reverse your last undo action.
As an alternative, you may use your keyboard keys to apply the Redo and Undo commands on color picker.
This fix has been applied to elements that allow color editing such as Background, Objects (One-Tone), Text, Line and Pictogram.
