What does getting rid of a color mean here? Are you asking to replace those pixels with new ones that are blue, and look smoothly like the rest of the turbulent region in that area? Or do you just want to have a white area in that region, so essentially nothing plotted?

LEt's say you want to change the values beyond a given value val (a number) into NaN. Use:
u(u>val) = NaN ;
isnan is afunction used to check whether a value is nan or not. You can check after replacing values with NaN using:
u(isnan(u))
