Linedef Type 16
From SRB2 Wiki
Linedef Type 16, the Colormap special, floods a certain area with a certain color at the specified intensity. When setting up the Colormap special, the color and intensity used is taken from an HTML-like color code, specified in the Front Above texture of the special linedef.
The format used for the Above texture is #RRGGBBA, where RR, GG, and BB are two hexadecimal digits for determining each color: red, blue, and green, respectively. The A at the end stands for "alpha", and is a number or letter indicating the intensity of the colormap from A-Z, and then 0-9, with A being the most transparent and 9 being the most opaque. Note that the alpha value is not hexadecimal.
Tag the special linedef to the sector or sectors that will affected by the colormap. It generally does not matter what sector the special linedef is tagged to, but tagging two colormap specials to one sector is unadvised, as this can cause problems.
Note that OpenGL handles colormaps differently than from Software mode. While Software mode may appear to flood the sector adequately with the specified color, OpenGL handles the intensity differently so the effect may not be as strong. Also, OpenGL's higher plethora of colors allows for a closer display of the specified color; in Software mode, the specified color is adapted to the limited 256 color palette.
