I am unable to save and add colors to a color picker control in Umbraco 7.7.6. While trying to add colors to a color picker control at the time of creation or trying to edit the colors on an existing control, I can add the colors I desire in the UI, however when I select the Submit button, the color changes are not saved and nothing happens. I have to choose the Close option to close the color picker setting window. The default color of black is the only value saved upon creation. I have tried several different possible workarounds posted in other forums such as: different browsers, created a separate tab just for colors at the top of my Document Type, adding all colors at time of creation vs editing colors on existing, all failing to resolve the issue.

What am I doing wrong?
