I'm plotting a heatmap with values ranging from -10 to +10 and I would like the negative values to show up in shades of blue and the positive ones in shadea of red. Basically, I want exactly what the RColorBrewer palette RdBu does but with more of a gradual change (the RdBu can only give me 11 distinct colours). Any suggestions?
