First of all I never said red fades to magenta. I said red fades faster than yellow. Look you can google it if you want to read the science I'm sure. My experience is from the 30 year printing industry knowledge I have and not with baseball cards specifically. I also didn't state it was just pertaining to baseball cards. I was responding to the general comment that yellow fades first in printed pieces when exposed to light. I am not a scientist and have not conducted my own experiments. I've read it and it's been discussed in printing industry publications. I don't care if I'm right and am not going to get into a whole big deal over it. I simply shared a bit of knowledge I have on the subject from experience. Test all the cards and write as much as you'd like about it but I have much bigger things to attend to than this topic. I'm starting to understand why a lot of people don't post and just lurk on this board. LOL.
