12.5 Colors

In the gEDA/gaf schematic and symbol file format colors are specified via an integer index. The relationship between integer and color is based on object type. Each object type typically has one or more colors. Here is a table of color index to object type:

Index	Object type
0	BACKGROUND_COLOR
1	PIN_COLOR
2	NET_ENDPOINT_COLOR
3	GRAPHIC_COLOR
4	NET_COLOR
5	ATTRIBUTE_COLOR
6	LOGIC_BUBBLE_COLOR
7	DOTS_GRID_COLOR
8	DETACHED_ATTRIBUTE_COLOR
9	TEXT_COLOR
10	BUS_COLOR
11	SELECT_COLOR
12	BOUNDINGBOX_COLOR
13	ZOOM_BOX_COLOR
14	STROKE_COLOR
15	LOCK_COLOR
16	OUTPUT_BACKGROUND_COLOR
17	FREESTYLE1_COLOR
18	FREESTYLE2_COLOR
19	FREESTYLE3_COLOR
20	FREESTYLE4_COLOR
21	JUNCTION_COLOR
22	MESH_GRID_MAJOR_COLOR
23	MESH_GRID_MINOR_COLOR

The actual color associated with the color index is defined on a per tool bases. Objects are typically assigned their corresponding color index, but it is permissible (sometimes) to assign other color index values to different object types.
