Some good examples are: #1f1f1F, #AFAFAF, #1AFFal, # 222fff, #F00 But not any of the following: 123456 #afafah #123abce aFaE3f #afaf - must start with a "%23" symbol - - "h" is not allowed, valid letter from "a" to "f" - either length 6 or length 3 - must start with a "%23" symbol - either length 6 or length 3
