Color

Color is defined in two ways, by palette_id with color_id and by RGBA values (all of these are defined in the node table).

• Press '-' or '+' key to change color_id.
• Press ALT+'-' or ALT+'+' to change palette_id.

Note that users can set custom colors (in the GUI, or table), but when they do, the RGBA color will not correspond properly with the palette and color ID's. Also note that in the GUI if you change either palette or color_id, it will automatically set the RGBA color and the custom color will be lost.

Another exception is with 3D models, changing geometry to a custom 3D model will automatically change the RGBA values to 100% white (for texture mapping to appear in it's natural color), but the color & palette ID's will be left unchanged, when switching back to the set of hard-coded (geo) primitives, the color will revert back to its original ID values.

The additional palettes are generally a gradient (of 128 or 256 elements) between two colors, however some are more complex, such as the 'rainbow' palette.
