Trump’s ‘American Flag Blue’ Reflecting Pool Reverts to Green Amid Algal Blooms

The Reflecting Pool near the Lincoln Memorial and Washington Monument underwent a $14.2 million repair project. Former President Donald Trump directed the pool be painted “American Flag Blue.” The color change was meant to restore a vivid blue appearance. Soon after the work, algal growth appeared in the water. The algae turned the surface green, undoing the intended hue. Officials attribute the bloom to environmental conditions post‑repair. The green water has drawn public attention and criticism of the project’s outcome. City authorities say they will monitor and address the algae to restore the pool’s appearance.
