Is it possible to have the constellation lines in more than one color? For example is there a way to make some blue, some red etc.?

Unfortunately, no. Maybe that'll be possible in a future version of Celestia.

However, in principle one could create a CMOD Mesh line object that consists of differently colored lines between locations in space.

What would be a typical application for multicolor? Just to make the sky more colorful?

Since Selden's reply started with "Unfortunately", he also must have had an application in his mind...

The use of different colors would make it easier to recognize different constellations, especially those which intermingle.

Also, when illustrating science fiction stories, it is useful to be able to portray travel routes between stars, with different colors used to represent different characteristics at different times, whether difficulty of travel, use by particular trade or political organizations, or the progress of military campaigns.

An example of the use of a CMOD model to illustrate trade routes of C. J. Cherryh's Alliance/Union novels is available at http://www.lepp.cornell.edu/~seb/celest ... index.html

That was the reason I was asking. I'm trying to make the star trek universe based on the books Star Trek Star Charts (2002) and Star Trek Maps (1980)
Both have trade routs and shipping lanes in different colors.
