Red is a fleeting color, particularly noticeable on some older art prints.
I once had a litho of a woman by an artist named Marie Laurencin from France.
I was told my picture should have had a fair amount of red in it and there was none noticeable anywhere.
I found the catalog raisonne and sure enough there was lots of red at one time. It was printed in the 1930's.
I will post pictures of 3 different UL stickers. While there is no evidence of red in the yellow sticker in question, you can see on the other 2 that it is not difficult to imagine the rest of the red coming off of them. In the close up you can see yellow under the red. It is quite possible I have a well cleaned UL sticker in need of a restoration which I will just leave alone!
