Add color picker to Conditional Formatting Rule Manager
To select a color in the Format wizard, a color picker would be very helpfull instead of entering hex values manually.
I cannot think of another modern day product where I have to enter a hex value for a color without the ability to use a color picker. This means I have to go to a different product that has a color picker, select the color I want and then copy the hex value over to your product. Doesn't that seem a little silly?
