To change the Scaling Function (how pixel values are binned into color levels): . ... For example, the basic grey-scale color map specifies no intensity for any color at the lowest color level, full intensity for all colors at the highest color level, with the red, green and blue intensities varying linearly for intermediate levels. ... At low bias, low color levels (i.e., low pixel values) will have non-zero intensities, while at high bias only high pixel values will have non-zero intensity. ...
