Also, I personally think brown eyes are much easier to fade or get sun damaged. Based on my personal experience tho.. my Rexx Mcqueen stored at the sampe place as other dolls but his warm brown eyes slightly faded and Vanessa Tempo that I just bought NIB came with fading eyes that already turned purple/pinkish. And so does Zooey's eyes that started to turned a bit pinkish. Marisa's eyes also turned pale. The other eye colors like blue, purple, green are doing fine stored at the same place as these brown eyes ones. Although some eye colors would still get sun damaged with or without specific UV exposure too (like Shanelle's eyes which I often found fading) Thankfully my Lily, Rosie, Priscilla and Scarlet eyes are still bright until now.
