Detailed explanation-1: -The RGB model uses 8 bits each–from 0 to 23–for red, green and blue colors. Each color also has values ranging from 0 to 255. This translates into millions of colors–16, 777, 216 possible colors to be precise.
Detailed explanation-2: -RGB-Three Numbers one each for red, green, and blue. 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.
Detailed explanation-3: -You can only represent 256 possibilities with 8 bit since it is 2^8=2*2*2*2*2*2*2*2=256 . So no. For 24-bit colors. 255 is thus simply defined as the maximum intensity of red/green/blue a monitor renders.
Detailed explanation-4: -A color’s RGB value indicates its red, green, and blue intensity. Each intensity value is on a scale of 0 to 255, or in hexadecimal from 00 to FF. RGB values are used in HTML, XHTML, CSS, and other web standards.
Detailed explanation-5: -A higher figure means more light. The higher the RGB values, the lighter the color. The lower the RGB’s, the darker the color. We set RGB to 0, 0, 0 and got black.
