Not a dumb question at all.
To start out with, yes you would be looking to remove any obvious colored tint, but you should read up on this a bit and and get as full an understanding as you can about that to adjust, what to look for and why. Using a calibration aid disk such as AVS HD709, Spears & Musil, Avia, or even Disney WOW might be best. But if you set the 2-Point to the "Inner" pattern and see the R,G,B contrast and brightness settings, you can check to see if there is any red, green, or blue tint to them. Usually, it would be most noticeable in the lighter "contrast" screen. And make small changes to see the effects. You want to get the lighter white screen actually a very light gray. Most people want to go to much towards blue if unfamiliar with the "colors" of gray. The lower "brightness" R,G,B screen may be closer to gray than the the first contrast settings of R,G,B so may not need much correction.
If you chose to do this, make sure you check it with a good B&W DVD or Blu-ray movie. Young Frankenstein or something like it will work. If the gray scale is off and shows any tint then you may likely see it. Of course, this is no substitution for using one of the calibration aid disks mentioned above, or best yet, using a good quality meter ($500 to $3,500 or more); but if the 2-Point is visibly off you can get it a bit closer to gray and improve color and picture quality a bit more than what it was.
Basically, you want to adjust the red , green and blue values in slight increments to remove any hint of color in the light gray and then dark gray screen, being careful to not get it too "blue gray". Once you've arrived at something that looks reasonably "gray", try a B&W DVD or Blu-ray movie, or one with B&W content like the still pictures in Sea Biscuit ( a good reference movie by the way). BE sure to write the values down so if you wish to change them a little, you know where you started. And, of course, if you think it's just made it worse, return all the values back to zero and leave it or start again.
Be aware, that all you are trying to do here is remove any really obvious visual tint to the gray scale and improve it a bit so over all picture quality may be a bit better than out of the box. This does not amount to "calibrating" your TV. It will get the gray scale a bit closer though, if there are obvious tints to both 2-Point screens. The lighter contrast R,G,B values may need more changes plus or minus than the lower or darker screen.Here
