[BioC] different color for a subset of points on heatmap

The easiest way I can think of:
One would be give those genes a different set of values. So if all your data is between -5 to 5, have the special genes from say 10 to 20. Then you can send it a set of colors that covers everything.
Here's an example where half is positive and half is negative. You can see the transparent colors in half of the columns as opposed to the non-transparent ones otherwise.
You'll need to be a bit careful to get the colors to match. I put the 1 and -1 to make sure that we cover the range and the colors and and values match.
