Saw this on Monday night coming home. The colors were slowly fading through some blue-teal-violet shades, water-like in a way. It almost looks internally illuminated through frosted glass, though we know that's not the case. It think it would be easily visible from downtown or across the lake.
Whoever did the install needs to make a return trip to fix the aiming of some of the fixtures, though. Even in the pic above, if you look about 10 panels from the left, you can see how that fixture is aimed to high and there is a darker area near the bottom. This happens all the way around both towers and detracts from the otherwise really nice light feature.
