Does it make sense to reuse COLOR_FOR_DARK_BACKGROUND here?

I guess we can use, word color is also in RRGGBB format, good catch 👍 .

Related to #230.
Few notes about implementation. Currently we may have cases when cell background color is set to a dark color(like black). In Office this is handled automatically and they convert text into white(if there is not custom color set for text). I also tried to handle this case by checking the color brightness using this formula: http://alienryderflex.com/hsp.html. This way if we detect a dark color we convert text to custom white color.
