8.2.1 Color Ramp

For the PseudoColor visual, the color ramp is a set of color cells reserved for display of images. By default, the color ramp is filled with a greyscale, so that displayed images are greyscale images. The user can change the display colors using the tvlct command, which modifies the whole color ramp based on the red, green, and blue values specified in the tvlct command, using linear interpolation.
