Want to create a random color in Java? With a bit of math, plus Math.random(), it’s pretty easy.
A bit about colors
Colors on the computer are made up of a red, green, blue triplet; typically called RGB. And each of the 3 pieces can be in the range from 0 to 255. Java also allows us to create a color using floats for the values in the range of 0.0 to 1.0, or from 0% to 100% of that color. We’re going to use the floats.
As an example, pure red will have an R value of 1.0, a G value of 0.0, and a B value of 0.0.
So we know what numbers we need, but we want ’em random.
