Duly noted.  Perhaps those #defines should be relocated to color.h?  If
we still wanted to provide a color_name type we could use
GIT_COLOR_NAME_RESET et al.  That would give us something like:

#define GIT_COLOR_NORMAL	""
#define GIT_COLOR_RESET		"\033[m"
#define GIT_COLOR_BOLD		"\033[1m"
#define GIT_COLOR_RED		"\033[31m"
#define GIT_COLOR_GREEN		"\033[32m"
#define GIT_COLOR_YELLOW	"\033[33m"
#define GIT_COLOR_BLUE		"\033[34m"
#define GIT_COLOR_CYAN		"\033[36m"
#define GIT_COLOR_BG_RED	"\033[41m"

enum color_name {
	GIT_COLOR_NAME_NORMAL
	GIT_COLOR_NAME_RESET,
	GIT_COLOR_NAME_RED,
	GIT_COLOR_NAME_GREEN,
	GIT_COLOR_NAME_YELLOW,
	GIT_COLOR_NAME_BLUE,
	GIT_COLOR_NAME_MAGENTA,
	GIT_COLOR_NAME_CYAN,
	GIT_COLOR_NAME_WHITE
	GIT_COLOR_NAME_BG_RED
};

/*
 * Map names to ANSI escape sequences.  Consider putting this in color.c
 * and providing color_name_get_ansi_code(enum color_name).
 */
const char* git_color_codes[] {
	GIT_COLOR_RESET,
	GIT_COLOR_BOLD,
	GIT_COLOR_RED,
	GIT_COLOR_GREEN,
	GIT_COLOR_YELLOW,
	GIT_COLOR_BLUE,
	GIT_COLOR_CYAN,
	GIT_COLOR_BG_RED,
};

That conveniently offers clients access to both the raw escape codes and
a clear type for storing/handling colors.
