[SOLVED] Expected Range: Red Green Blue

[AndrewM16921]

I get the following error:

Exception in thread "AWT-EventQueue-1" java.lang.IllegalArgumentException: Color parameter outside of expected range: Red Green Blue

However, from what I've done I do not see how.
Take R (R, G, and B work the same way here). Regardless of what it becomes, I use R % 256, so the value should be between 0 and 255 (inclusive). How then is this value outside of the expected range (which is 0 to 255, right?)?

for(int x = 0; x < WIDTH; x++)
{
	for(int y = 0; y < HEIGHT; y++)
	{
		if(gen.nextInt(100) <= coverage)
		{
			int R = primColor.getRed(),
			G = primColor.getGreen(),
			B = primColor.getBlue();
			
			R = (R + (gen.nextInt(2*range)-range)) % 256;
			G = (G + (gen.nextInt(2*range)-range)) % 256;
			B = (B + (gen.nextInt(2*range)-range)) % 256;
			
			g.setColor(new Color(R, G, B)); //error here
			g.fillRect(x, y, 1, 1);
		}
	}
}

Oh, I figured out why lol.

R = Math.abs((R + (gen.nextInt(2*range)-range)) % 256);
G = Math.abs((G + (gen.nextInt(2*range)-range)) % 256);
B = Math.abs((B + (gen.nextInt(2*range)-range)) % 256);

There. ^_^
