22+ Idl Color Tables. To define a color table in graphics functions such as image and map , use the rgb_table. These color tables are defined in the file colors1.tbl (located in the main idl directory) unless the file keyword is.
With the colortable function, you can specify the parameters to create a custom color table or load a system color table with specified parameters. The modifyct routine lets you create or modify and store a new color table. It specifies the mapping between data value and color/intensity—or, for a grayscale image, the mapping between data value and intensity.
