The Spanish word color often signifies the colour red. Colorado (coloured) is the a description (and name) of a place with a lot of red-coloured rocks.

We were flying to Mexico City over some of the red, red rocks of the American Southwest. I wasn’t exactly sure where we were but there were almost no signs of life in this beautiful barren country. An abstract painting in red. This inky blue-black river reminds me of the intensity of water colour in Lake Powell. There are no signs of life other than a squiggly line that may or may not be a road; if it is there is nothing travelling along it. Lake Powell, the same blue-black water, but the land is a paler red and people live and play there. Although now that I look at the photo I see there is no one there other than us.
