Wish we could have highlights for hair
I wonder why they haven’t implemented it yet?
I think we've mentioned this before, we know people are always asking for it but there are a handful of big issues for why we haven't tried to do it. One is that we'd have to hand-draw highlights with 6 different variations for every existing hairstyle -- normal, turned around, wearing a cap, wearing a cap turned around, wearing a helmet, wearing a helmet turned around -- so that alone would take a long time to do. Then we'd have to do the same for bangs as well (x6 for each of the variants). And we'd have to decide if we just add streaks/highlights across the board to everything, people would probably want to see different ombre fading too and be asking for that, so we'd have to think about if we add multiple types of highlights or just tell people they can only have one type.
After that, there'd be the issue of how you would select a highlight color, since PLP and Gamerias use different systems for selecting colors we'd have to redesign one or both to handle a third palette chooser that we'd have to always have available, even if someone doesn't care about changing hair highlight colors. And the last thing would be adding all of those highlight layers/accents onto the hair would add a bunch more rendering and processing the phone/tablet would need to do to handle more graphics on-screen (even if someone's not using highlights), so it runs of the risk of PLP and Gamerias running a bit slower whenever a worker is on screen because of dealing with the extra layers in the hair.
So it's quite a lot to deal with!
