Well I was in a rp guild many years ago that only allowed the dark grey or black colors to be worn and I found it depressing. I was always the rebel and loved to dye my hair pink and wear colorful outfits. Needless to say my gm had quite a time with me!
I understand the way the rp community likes to present themselves and I appreciate that, it's a big world and imo there is room for everyone and their individual playstyle in it. Personally I enjoy variety. The new colors will undoubtedly find a following with some, as evidenced here, but I just find them plain. But you have given me hope that maybe I can sell it to someone.
