Though I agree on the color change which would attract more publicity on the
wing, this would most likely only make impact on the fashionable side of the community
who wouldn't mind paying extra for a nicely colored wing
(let's say the effects of the wings were not enhanced).
Unless the mode/pvp tokens amount of which the wings can be obtained is drastically changed,
I don't think people would choose to get them over a Sacred Wing which is
at least 3k upwards (except for SGW).
On the color changes, +1.
On the implementation of it (including effects change/ reduced pvp tokens amount/ making it questable),
I think it's not too ideal to make that much changes on an existing wing which has
basically not established its market value so far.
