Random Color

> Hello i need a basic way tocreat random colors. I am making a program that displays random shapes and I need those shapes to have random colors. PLease help


// In your class:
static Random random = new Random();// ... Later, in a method:
Color randomColor = Color.getHSBColor( random.nextFloat(), 1.0F, 1.0F );

You actually get a lot of junky colors when they are too random, so it creates a more aesthetically pleasing effect when they are less random. For instance, you can create an array of colors by incrementing the first parameter of getHSBColor() from 0 to 1.0 (increment size being the inverse of the array size, of course), then use that more limited "spectrum" for a more visually pleasing effect.
