Hi, 
I have scientific data from a microscope with 2 channels. I have to merge
these two channels, but unfortunately there is only one color map. So both
channels ( Reprensentation: "Volume") are expressed in one color. I need two
color maps,so that the channels have different colors . My ParaView Version
is 4.2.0. 

Is anyone able to help me with detailed steps?

Thanks
