Faction Icon Color Issues

Kuroi_Sin - Dreamweaver

Ok, so a couple weeks ago I submitted my faction icon and it made it into the game with this last maint, but the color was a bit off. The file I sent in was this. The file that made it into the game was actually this.

The format I uploaded was a 32-bit bitmap with an alpha channel for transparency. The green was R0 G255 B0 which is the most base green that computers can display, so pretty much any bit-depth or format can display it without issue, especially a 32-bit bitmap.

Can anyone explain why the green was degraded to this sea foam green that is seen in-game?
