Plugin breaks on non-english systems

[ric20007]

The plugin fails to start on systems where the decimal point is not "." when parsing a color, some countries use a different decimal point separator and it's making the plugin crash.

The exception I get when starting the game:

[Error  : Unity Log] FormatException: Input string was not in a correct format.
