Hi, I have a colorbar that assigns the color blue to the value 0. I'd like to specifically assign the color 'white' to the value 0. How can this be done? Thank you!

If you want white color exactly at the center corresponding to value 0 then you will need to make the limit of caxis() symmetrical around zero. I suppose that in your case min value is negative. Therefore try
maxLimit = max(abs(min), abs(max));caxis([-maxLimit maxLimit]);This works:
ramp = linspace(0, 1, 400);ramp = repmat(ramp, [400, 1]);imshow(ramp);colormap(jet(256));colorbar;
What's different with you? What range does your image have?
