You can use the blue texture of the combat unicorns for the pegasus. At the same time, these decorative elements shouldn't stick out; but they can always be removed. And the wings can be adjusted separately to a blue hue.
Unfortunately, the pegasus has its own geometry (which is placed in the bin folder), and it doesn't take the scarf into account. That's why it looks like this:

Naturally, this is not what I want. =)
Update: I photoshopped it as best as I could; the horse looks better now.

Update 2: I extracted the angel wings from the downloaded pegasus again; they are very bright, and I photoshopped the color, and it turned out very well (I'm surprised). I'll still work on the icon.
