Isn’t group velocity (transmission speed) what you want to fix for chromatic aberration issues?

> For light, refraction follows Snell's law, which states that, for a given pair of media, the ratio of the sines of the angle of incidence θ1 and angle of refraction θ2 is equal to the ratio of phase velocities (v1 / v2) in the two media, or equivalently, to the indices of refraction (n2 / n1) of the two media.

Huh, ok. I stand corrected.
