I do understand that the intent was to use layers of prism shaped quartz to
form the "Light" panels, do to there refractive abilities. And the idea of
covering said panels with a deep layer of liquid water works very well as a
radiation shield (water is always the best for cheap shielding). Water should
act as a very effective light filter for a colony, as well.
All in all, I can easily see liquid water rather than ice as a covering for
the "light" panels. But that doesn't mean that Tomino actually used that idea
in Gundam. We still see Mobile Suits hovering along a panel's surface like an
air hockey puck with their foot thrusters and tread shape acting as a plenum
for a very shallow ground-effect. And no spray to speak of.
