Thanks Andy, I'll look into this.<div><br></div><div>Ken, I think I already tried something similar. I wrote a program to "merge" two scalar data sets as colours (3 vector) according to a colour scheme, then turned off "map scalars". Is that what you mean? This works ok but I think it means I can't use any of the colouring and visualization options in Paraview to manipulate the appearance (e.g. change the colour lookup scheme, set logarithmic scale etc). I have to rerun my program to change any parameters.</div>

Is it the case that if you color by a vector array comprising unsigned char, ParaView can color the surface directly using those colors (turn of Map Scalars)? If that’s the case, Tristan can create a filter (perhaps by using the Python Programmable Filter)) to create such an array.<br>

there's no way of doing it. If the latter, then the Object Inspector<br>
allows one to change the color for the "active" mesh. You change<br>
what's active by choose a different mesh in the pipeline browser.<br>
