Hello, I am using cbrewer for my colormap. However the value 0 is not exactly white (attached jpg image). I have played around with the n, but nothing seems to change.
n=256
colormap(cbrewer2('RdBu',n));
How can I make the 0 value true white?
Thank you

This doesn't have anything to do with the particular colormap. This has to do with the fact that the colorbar limits are not centered on zero.
Try:
caxis([-8 8])
