Working with Colors

Throughout libxlsxwriter colors are specified using a Html style RGB integer value. For example with a Format object:

format_set_font_color(format, 0x3030E0);

For convenience a limited number of color names are supported:

The color names and corresponding RRGGBB value are shown below:

Color Define Value
Black LXW_COLOR_BLACK 0x1000000 (note)
Blue LXW_COLOR_BLUE 0x0000FF
Brown LXW_COLOR_BROWN 0x800000
Cyan LXW_COLOR_CYAN 0x00FFFF
Gray LXW_COLOR_GRAY 0x808080
Green LXW_COLOR_GREEN 0x008000
Lime LXW_COLOR_LIME 0x00FF00
Magenta LXW_COLOR_MAGENTA 0xFF00FF
Navy LXW_COLOR_NAVY 0x000080
Orange LXW_COLOR_ORANGE 0xFF6600
Pink LXW_COLOR_PINK 0xFF00FF
Purple LXW_COLOR_PURPLE 0x800080
Red LXW_COLOR_RED 0xFF0000
Silver LXW_COLOR_SILVER 0xC0C0C0
White LXW_COLOR_WHITE 0xFFFFFF
Yellow LXW_COLOR_YELLOW 0xFFFF00
Note
Black in Html is actually 0x000000 but LXW_COLOR_BLACK is defined as 0x1000000 to avoid confusion with an undefined or Zero color value. It is converted to the correct Html code internally.
