Videopinball colors in stella 2.4.2 are not accurate?

[Keatah]

Is it possible to assign a separate palette definition file for each rom? When I play videopinball on Stella 2.4.2 the playing field seems to be a bit heavy on the violet/purple side of the spectrum. All other emulators seem to reproduce the correct dark sky-blue hue for the bumpers and whatnot.

 

Best regards!
