I have grayscale image with values 0, 11-max(image). I want to show 0 as black , and 11-max(image) as different type of red.
my questions are:
1.how to change the colorbar accordingly? I dont mind showing 0-11 as black, but it will be best if the values 1-10 will not shown at all at the colorbar. or , in other words, can I show at the colorbar only the values :0,11-end?
2. how to make the quantization of the red seem good? (so that the human eye could make the different between the shades )
please help?
thank you.

You cannot use colorbar and have a range omitted. You could create your own colorbar replacement.
For the quantization you probably cannot do better than linspace() of the red values between some minimum and maximum in the 0 to 1 range,with number of steps equal to the greatest max value minus 9
