I've noticed this when viewing DVD movies through the component inputs on both my home TV & DVD player and through component inputs on displays at work.
Even after running DVE through all of them via component cables, I found component to be just a bit too rosy/pinkish red in the skin tones for my liking. I ended up really enjoying watching material either through S-Video or composite(!) actually. I didn't feel like I was "forcing my mind" to accept the reddish tones as much as I was in Component. Is component in both home and work cases really accurate and I'm just not used to seeing that much red/pink in flesh tones - or are the component inputs at work and at home both flawed(coincidence)?

Are you running at 480p via component? I ask because my set has separate memories for each scanrate (480i, 480p, 1080i) it accepts, including color decoder settings for red, green, and blue. Perhaps your display has separate memories as well, so you could be seeing varying degrees of red push over your different inputs. Colorspace twisting errors are also more of a factor with component than with HDMI, IIRC.

When I set the Sony DVD/VHS combo to output 480p via component at work, the 48" plasma displayed a 20" diagonal totally greenish yellow picture! Fortunately the Sony was smart enough to prompt me "Do you want to keep this setting or cancel?" I selected cancel and thankfully ended up back in regular 480i output. Evidently this plasma - about 3-4 years old, doesn't stomach progressive well! ;)

I don't have decoder settings in my home TV's service menu, and they don't exist or are unaccessible on the plasma at work.
So you're saying that Component is more sensitive to changes in colorspace than is composite or S-Video? Good to know.
But in both cases the edges of subjects against backgrounds were much sharper than composite. This allowed me to set sharpness just by looking at the edges of shiny objects against dark backgrounds, and really SEE where sharpness was kicking in - and stop right there.
But still - for both my home set and the "pro-sumer" plasma monitor(non tuner model) to have rosey component - that's odd.

I've seen the same thing as far as component having a ruddy complexion on my set, compared to digital sources (HDMI, DVI). Recently, the HDMI output on my satellite receiver quit, and I went back to its component outputs for HD until its replacement arrived. I was very surprised to see the rosy picture you're describing. My first thought was grayscale changes, but a quick check showed the grayscale was OK. So, it had to be from somewhere in the color decoding chain for component.

I wouldn't say that it is more sensitive. It is, however, a fact that component can carry both SD (Rec.601) and HD (Rec.709) signals, while composite and s-video carry only SD signals. With only one colorspace to deal with, they don't have the potential for colorspace twisting errors that component does.
