Improve word cloud contrast for dark backgrounds
The WordCloud presentation style is very impressive, but when you use black or dark background colors/images most of the words in the cloud are hard to read. It seems only the two largest words use the configurable text foreground colors (secondary and primary). It would be nice if to have at least configurable brightness for colors used by all the other words.

Thanks for your response. I was using a black background, but the contrast is even worse when using a dark background color. It's readable on a computer screen, but people with certain vision impairments would have a difficult time. However, when using a projector to display the wordcloud/presentation, the low contrast can make it near impossible to read some of the words.
Here is an example with a black background to illustrate the low contrast. Note that the two largest words are displayed using the configurable primary and secondary colors and thus have high contrast: http://tinypic.com/r/v773hh/9
Compare that to this screenshot where the colors have been inverted. When the background is white, the contrast is excellent: http://tinypic.com/r/294gf86/9
