Colour of beauty is what some randomparents, who seem to have a certain hearing damage, understand when you tell them that you are playing Call of Duty
Mom: What are you doing?
Son: I'm playin' Call of Duty.
Mom to Dad : Mhm he's playing Colour of Beauty again... I still don't understand why this brutal game has such a soft name...
When you embarrass yourself you colour/paint your face red. Red being the colour of embarrassment since people's faces become red when they are embarrassed.
T: "Weather report says it's going to rain soon"
V: "I don't think so, they're never right. Let's go out"
T: "Don't blame me if you colour your face red"
*Starts raining just as we step outside the house*
