Use Post-It notes to color your dashboard and miss that red warning light that would have actually caught your eye when it first came up but was lost in the Christmas lights that pass as your dashboard. And now your car is f*cked. There's a very good reason why your dashboard is boring and color coded by the manufacturers. They employ psychologists to test and check their designs. They want you to get the car seen to a.s.a.p.
I'll take the pretty colors, please.
