By specification this is a sample RTF color table group:

{\colortbl;\red0\green0\blue0;\red0\green0\blue255;\red0\green255\blue255;}


Currently , if there is a whitespace separator (" ") before the tag delimiter (";") an RtfColorTableFormatException is thrown, for example:

{\colortbl ;\red255\green255\blue255 ;\red79\green79\blue79 ;}


Instead, such documents could be easily imported by trimming the whitespace.
