Sylvari glow vs no glow
The glow on Sylvari bodies is called Bioluminescence. This means that they sort of work like a glow in the dark ball. They absorb light during the day and expel it in the dark. So, it wouldn’t really work if we glowed all through out the day. We wouldn’t have time to absorb enough light for that to work.
Have you tried messing around with skin patterns + colours more? Try colour compliments?
My Banana skinned Sylvari’s bright blue eyes for some reason a really dull and almost black during day time. But the bright purple hair against the gold skin makes her stand out anyway.
