# al\_color\_html\_to\_rgb(3)

Allegro 5 API

## NAME

al\_color\_html\_to\_rgb - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro_color.h>
  bool al_color_html_to_rgb(char const *string,
     float *red, float *green, float *blue)
  ```

## DESCRIPTION

Interprets an HTML-style hex number (e.g. #00faff) as a color. The only accepted formats are “#RRGGBB” and “RRGGBB” where R, G, B are hexadecimal digits \[0-9A-Fa-f\].

Returns true on success, false on failure. On failure all components are set to zero.

*Note*: the behaviour on invalid strings is different from Allegro 5.0.x.
