Toshiba has always said the Warm setting is the most accurate. However, I remember a couple of years ago one of the HT magizines did a test on a Toshiba widescreen and it turned out the Medium setting was more accurate. I know on my 2 1/2 year old Tosh widescreen the Warm setting is just too red. Toshiba may have corrected this by now, however I'd say just go with what looks best to you.
