Trump wanted the Reflecting Pool ‘American flag blue.' Algae is turning it green.

The Lincoln Memorial Reflecting Pool appeared green on June 15 because of algae growth. This environmental condition occurred despite the preference of Trump, who wanted the water in the Reflecting Pool to be 'American flag blue'. The current green coloration is a direct result of the algae present in the water, shifting the visual appearance away from the specific blue shade desired by the former president for this historic site.
