I can't wear pale pink shirts, but a more medium to watermelon pink gives me a nice healthy glow. Soft gray shirts make me look like the walking dead, but charcoal offers nice, rich contrast
In the multiple corduroy suit pics (above) I wouldn't choose any of them because they all have acidic yellow or golden undertones. I know from experience that I look best avoiding these colors.
I always get a kick out of GusW's posts because of the writing style. They almost always use the first-person and have a short, reportorial delivery and can-do, positive note. It's vaguely like the style of 1950s advice columns. I can't put my finger on it, but it's something that has amused me for some time. That first sentence cracks me up. Sounds like something Ann Landers would write.
I agree that one's good/bad colors may have some sort of biosignature unique to each person and it's best to figure these out immediately and avoid the bad ones like the plague.
