Description : Are rivers in real life brown, greenish brown, brownish green, or kind of clear, but in pictures they're blue and turqouise, etc.?

Clear water will flow eventually anywhere, but particularly of ... plants, but usually the blue-green is a combination of reflected or refracted light and algae.
