What does 255 mean in RGB?
In RGB, a color is defined as a mixture of pure red, green, and blue lights of various strengths. Each of the red, green and blue light levels is encoded as a number in the range 0.. 255, with 0 meaning zero light and 255 meaning maximum light.

How do you read RGB?
RGB(255, 0, 0)
RGB defines the values of red (the first number), green (the second number), or blue (the third number). The number 0 signifies no representation of the color and 255 signifies the highest possible concentration of the color.
How do you mix paint with RGB?
To start mixing in RGB, think of each channel as a bucket of red, green, or blue paint. With 8 bits per channel, you have 256 levels of granularity for how much of that color you want to mix in; 255 is the whole bucket, 192 = three quarters, 128 = half bucket, 64 = quarter bucket, and so on.
What are paint color codes called?
