Although it looked all right in the Studio, in game a glitch appeared on all colors including the new one. I wanted to add one whiter recolor to NewSea's free Janice alpha hair YU183f (for personal use), so I followed the tutorial /thread/386/add-swatch-existing-hair-beginners with Photoshop CS6. I've read forum rules/FAQ, and tried searching for help without luck.
