It depends ! Sometimes the colours are dark / strong so they represent anger gloominess and stuff if it's pastel or let's say normal it could mean happiness if it's kinda of a neutral I believe it's normal or sad but like I said it depends cuz the colours vary in the characters as you see ! Callisto has a golden / red , Reynold has a pinkish colour , Derek has a greyish blue and I believe it has to do with their characteristics like hair and eye colour and I believe the emotions are the shades instead of colors

Idk if this will help but some people in social Platforms have been leaking spoilers and stuff which I don't mind and some of them were of Callisto and he loves Penelope so much that when she was sick he would always have a sword with him incase she dies he could suicide the other one is Vinny ?? Idk the gray white haired one ( I think that was the one you were trying to say ) and that he reincarnated many times which he would love Penelope ( I think I don't really remember too well ) and she wouldn't remember him and if you are talking about her older brother ( Derek ) is cuz he is incestuous trash who cant be recycled cuz he loves / likes Penelope yes she is adopted but that still counts and thats the reason he couldn't accept Penelope as his sister and a spoiler that everyone in the fandom of ditoeftv / vadtd knows and that's why I guess "he means death " other than that I cant help you much as I'm not a novel reader ! If anyone has read the novel or knows more spoilers I ask to please correct me if I said something wrong !
Can someone explain of what are the meanings of the colors in their percentages??
