A shot of the lower half of the falls.
I did very little editing, mostly just made it a bit brighter, and didn’t fiddle with the balance or boost the “color saturation,” or whatever it’s called.
I think the color comes from minerals and perhaps fresh-water algae. Pale blue? Pale turquoise?
The Crayola box (the big one, my go-to reference for art stuff) indicates “aquamarine,” but when I look online at a color chart, that’s way too green.
“Bluish” will have to do.
