Several of the coloring methods in the graphics form are used to color a range of values, as compared to a list of names. The actual coloring is determined by the color scale.
There is only one color scale available at any one time (out of the ten possible) and it is changed with the Color Scale Method chooser. Changing the values of Minimum and Midpoint change some of the proportionality values used in making the scale.
The colors used by the color scale are not the colors in the color map, so the Edit Colors part of the form will not affect the color scale colors.
