For Weiss' glyph:

White-affects gravity/push. Ruby was still using Crescent Rose to scale the cliffside.

Black-magnet or reverse gravity/pull. That thing hels Ruby down for way longer than it ought to have been able to.

Red-repels. This may be akin to the red Myrtenaster seen in the white trailer.

That's my theory.
