The color menu displays a list of available colormaps. Each frame in SAOtng can have its own colormap. A newly chosen colormap becomes the default colormap for new images in that frame (until changed by choosing another colormap). The current colormap is displayed below the menu.
The contrast/bias of the colormap can be manipulated using the right mouse button in the image frame. The resulting colormap is displayed in the colorbar below the image. See Adjusting Contrast and Bias.
The Invert Colormap menu option will invert the colormap values.
Users can add their own colormaps. See Adding New Colormaps to SAOtng.
