random thought: for people who have never used an oscilloscope (or at least never used a digital one), if you had to pick four colors for four scope channels to be, which four would you pick, and what order would you put them in?
(bear in mind that most oscilloscopes use a black background. but if you want to pick some light-theme colors too go right ahead!)

@starkatt Oh! I was thinking that, but we've never seen a blue phosphor CRT.
