How can i change the color of one mark in colorbar?

For example, I like the colorbar 'jet', but I want the cyan mark to be in different color. I was changing it manually but it's really tedious if I have a lot of plots. Can I change it in code?

Get the colormap values, find the respective color (RGB) you want to change and replace it with your desired (RGB) color. Check the below code.

[X,Y,Z] = peaks(25) ;
figure(1)
surf(X,Y,Z)
colorbar
c = colormap(jet) ;
title('original jet')
figure(2)
idx = find(ismember(c,[0 1 1],'rows')) ;  % get cyan color index 
c(idx,:) = [0 0 0] ;    % change cyan to black
surf(X,Y,Z)
colorbar
colormap(c)
title('Cyan in jet changed to black')
