Is the Danube really blue?



 The glacial lakes in Canada are really blue as they contain glacier dust. They are a delightful blue-green. 

When I was planning a trip down the Danube, I had friends who would warn me that it is not blue. As a volunteer children's art teacher, I did not explain to these friends about reflection and the fact that water is clear but takes on the  color of the sky.

The two photos above are examples. The top photo sees the river reflect the overcast. The river itself is not that clear from the ships' wakes, but the sky is gray thus the water is gray.  The bottom photo is of Budapest. It is a clear, sunny day. The water is very blue (bluer than this photo shows.)
