does a wurm's tooth proc from multicolored spells?

[Arix]

A multicoloured spell counts as all its colours. A white/green spell, for example, is both white and green, so will be affected by anything that affects either white or green spells. It will trigger Wurm's Tooth, Angel's Feather and Quirion Dryad, and can be countered by Flashfreeze.
