RGB color(R=red, G=green, B=blue) denotes definition of the color in the RGB color model. The result color is combined from the red, green and blue parts.

• The range of R, G and B parts is on the computer usually in the range from 0 to 255. This number comes from the representation on the computer where every color part can be stored exactly in one byte.

• Though the RGB color model is good for representing the color in the computer it is not suitable for adjusting color by the people. It is because the perception of the colors. People can say, that they want to have the color more brighter, but they cannot translate it to the RGB values. Because of that it is more natural to present color in other color model (for example HSB) for user interaction.
