M.1 Built-in color palette tables

Figure M.1 shows each of the 22 built-in color palettes, stored in so-called cpt tables. The programs makecpt and grd2cpt are used to access these master cpt tables and translate/scale them to fit the user's range of -values. The top half of the color bars in the Figure shows the original color scale, which can be either discrete or continuous, though some (like globe) are a mix of the two. The bottom half the color bar is an example of a discrete color scale build by using makecpt -T-1/1/0.25.

Figure: The standard 22 cpt files supported by GMT.
