Conditional Formatting options: have an option that has green, blue, and red

It would help our dashboard visualizaiton tremendously if there was a conditional formatting option that included the colors red, blue, and green.  The red and green define areas that a user can or has to input (Green = can, red = has to) and then we would like the summary on the column lists (a custom time list) to be highlighted a different color so the user can easily see the breaks of time.  

Honestly, expanding the color grid seems like an easy and sought after issue in Anaplan!
