No, not really on the color inaccuracies.
You're trying to correct a plasma. The filter approach to adjusting color on a plasma doesn't work. On a plasma, you're going to have to use a meter, signal source(calibration patterns (free)), software and learning curve.
Find the AV709 disc on this forum and you can download it for free. That'll help you with brightness and black level. http://www.avsforum.com/t/948496/avs-hd-709-blu-ray-mp4-calibration
If you do get a meter, software, etc. here's a disc with patterns suitable for a plasma. http://www.avsforum.com/t/1463980/masciors-calibration-disc
I'd recommend downloading both and taking a look around to see what they contain.
This presumes that your DVD or BluRay player outputs reference or at least near reference signals. If it's off, depending on how it's off, might present another issue to deal with.
