Yeah, I'm starting to think the glyph turned red because of the influence of Ruby's Semblance. The glyph is black and motionless at first, but as it turns red, the snowflakes inside begin spinning, faster and faster, and then BOOM!

From the blast, it looks like Ruby was using a regular bullet, so it wasn't just her using a rose petal bullet like what she used when fighting the White Fang in No Brakes. (Here's the best screenshot I could get of that. That red mist turned into rose petals. You have no idea how hard it was getting good screenshots of Blake and Ruby during that fight, or how hard it was to keep pausing to see what was happening, even though I was watching the whole thing at 0.25 speed.)
