External program will be created a image, for example
image(rand(100,100)*10)
colormap(rand(10,3))
I will add a colorbar by my function, it simple
colorbar
Now I only show part of the colorbar by colorbar('Ylim',[1,6]). But I want to change the color of the 5th color block, let it same as the last color block. (the 5th color block of the right image should be changed to the last color (of left image)).
No need to care about the Ticks of the 5th color block, (maybe showing like '>5', or any other string).

Try this:
image(rand(100,100)*10)
cmap = rand(10, 3)
colormap(cmap)
% Now put color in block 10 into block 5
cmap(5) = cmap(10);
colormap(cmap);
caxis([1, 6])
