That was indeed unexpected.
Maybe the development staff made it cyan for balancing purposes. It could be they try to make every wu range segment and color group have an equal amount of varied items. I don't know this for sure, it's just my guess, but usually developers try to do something like this in other games.

Sometimes the White group has items that visually have rose/magenta accent colors in them. If it's necessary for it to not be part of the magenta/rose/red color groups, then perhaps it could belong in White?

It decided to rebel lol. I uploaded it as rose and Cherche added it as rose but somewhere it decided it wanted to be cyan
But yeah, as Cherche wrote above she's now changed it back to rose

The change might not have stuck since the strawberry ice cream is still cyan. Who can guess the whims of dairy products?

@_@ try hitting CTRL +F5 and see if that refreshes the item, but uh in all technicality it is now Rose LOL.

I might be the only one that, as a lover of minor glitches like this, doesn't mind the strawberry ice cream I own still being labeled as cyan. Since the original glitch was fixed, it's like I have an exclusive item
