it's just the colour of the local sandstone - if it wasn't red it'd be something else. Plus the colour of sunrise and sunset accentuates it.

Actually, the coloration of the Navajo Sandstone which is predominant in the southwetern U.S. is colored by oxidizing iron or hematite. Some of the iron can even be seen in iron nodules (little balls) in certain areas. Some of the most interesting geology in the world can be seen and studied here in the U.S.

By the way, not all iron oxidizes into just reddish hues... some is yellowish, brown, green and even near white... which accounts for the gradation of colors near Sedona and the Grand Canyon.
