+ * vivid-color.c - A table that converts colors to various colorspaces
+ *
+ * The test pattern generator uses the tpg_colors for its test patterns.
+ * For testing colorspaces the first 8 colors of that table need to be
+ * converted to their equivalent in the target colorspace.
+ *
+ * The tpg_csc_colors[] table is the result of that conversion and since
+ * it is precalculated the colorspace conversion is just a simple table
+ * lookup.
+ *
+ * This source also contains the code used to generate the tpg_csc_colors
+ * table. Run the following command to compile it:
+ *
+ * gcc vivid-colors.c -DCOMPILE_APP -o gen-colors -lm
+ *
+ * and run the utility.
+ *
+ * Note that the converted colors are in the range 0x000-0xff0 (so times 16)
+ * in order to preserve precision.
