I recommend changing the colourmap; red-green colour-blindness is fairly common (something like 8% of men have it), which would make the figure closer to unreadable. While you're at it, center the colour scale at 0 (instead of 4%) so that the divergence in the colourmap has some meaning (and it's easier to distinguish positive/negative values).
