Not currently. However, adding support for custom color maps is in our
todo list.

We have no intention of replacing the use of Tcl with Python. Tcl is and
will be the main scripting interface for the ParaView GUI. However, we
are working on separating the core of ParaView from the GUI. This core
will be scriptable in any language VTK supports (tcl, python and java).
We will also develop a language independent (probably xml based)
interface to this core. This will also allow us (and everybody willing
to invest the time) to write clients (GUI) in any language we want. This
is in progress now and will start to appear in the next release (and
will be finished before 1.6).
