Fix a colormap between two values

Dear all,
I am trying to simulatine the imaging of an object from a camera and a depth sensor. I'd then like to plot the simulated image thanks to the scatter tool, specifying depth as colormap. I make a new image at each time step. The camera motion is towards the object (and the object rotates), hence the overall depth diminishes. However, at each time step the colobar is mapped from depth of that time step:
At t = 0:
At t = end:

I would like to "fix" the colorbar between two handpicked values [depthMin depthMax], so that the first image is generally blue and the last image is generally yellow (that the colorbar doesn't "slide"). And if possible I'd like to use Matlab embedded colormaps.
Do you know a trick to do that ?
Thanks for your help.
Regards

caxis([depthMin, depthMax])

I'm wearing a lab coat. Does that count?
Glad I could help!
