- New libgimpcolor functions: gimp_color_parse_hex() and gimp_color_parse_name().
- GimpColorHexEntry is now space-invaded. Though recognized color names
  and hexadecimal syntax are sRGB only (because CSS and SVG
  specifications explicitly say that this syntax is for sRGB values), it
  is possible to enter non-sRGB values with
  gimp_color_hex_entry_set_color().
- GimpColorSelection is now space-invaded.
