The RGB color model use a color coordinate system with three primary colors: R(red), G(green), B(blue) Each primary color can take an intensity value ranging from 0(lowest) to 255(highest) Mixing these three primary colors at different intensity levels produces a variety of colors. In the RGB color model, an arbitrary color within the cubic color space can be specified by its color coordinates: (r, g, b) for eg more the value of r more the texture has red tone
