Fact-check: “Painting the bottom of the Reflecting Pool in Washington DC blue will cause it to not reflect as well as it did when it was black.”
Verdict: Partly True (45% confidence)
The claim is mostly supported by optical physics and early visitor observations, but needs a key qualification. A black bottom minimizes light returning from below the water surface, which makes reflected images appear sharper and more dominant against a dark background — so switching to blue does reduce the perceived quality of mirror-like reflections. However, the physical surface reflectance (governed by Fresnel optics at the air-water interface) is unchanged by bottom color. The actual post…
