Well, i asked if you had enough of dunes and the only feed back I got was "pro-dunes" so here it is: a study in dune colours.
Those three photos were take with a half hour and within 100m of each other at a time when the light was changing quickly. It was around 6:00 at night.
With little light in the morning or the evening the dunes are grey, they they turn pink and orange and bright. At the noon hour especially on hot days they seem nearly white. Then back to bright orange or pink in the early evening and grey as the sun goes down...generally, but no two days are alike especially when you factor in the wind, the humidity (or lack off) in the air, the clouds...and everything else. Quite an amazing process really.
As you can see I am having quite a hard time putting three pictures on one blog...I've struggled with it long enough I think this is the way it will have to stay.
