Magenta
Apparently men have trouble seeing magenta color casts. Last night at work we just took 365 yearbook shots for the various schools' graduating seniors. Tom color corrected them and they all have a slight magenta hue. I noticed this too when I was training the new guy, Mike, to do color correction. All of the images that he corrected with white or gray backdrops had a very noticeable magenta cast (to me, at least). I pointed it out, and he said he didn't realize, so the next batch of correction he did he tried to compensate for it. Still magenta. Okay... um...... maybe try comparing it to mathematically pure 50% gray. Okay, now he sees it. Says he'll correct it. The next batch. Still magenta. .......... what's going on? Tom has been doing the same thing, but that's just because he's busy and goes fast, or so I thought. Then I remembered talking to Mele a few months ago about how she used to correct and develop photos at a large photo lab (before digital came along) and all of the images that the guys developed were magenta, and all of the women's were spot on - gray was gray, not pink. So is it genetic? I'll have to do a bit of research into this. If it is, I don't have the gene. It's probably linked to the colorblindness set of genes, since many men are colorblind but almost no women. I can see magenta without a point of reference. Everyone can see magenta when compared to solid gray, but if you just have a picture with a magenta tint, guys can't see that something is wrong. Blue tints they can see just fine. Hmmmmmm.................... Anyone ever heard of anything like this?
