Originally posted by mischivo This is a great image with great colour, much like everyone else has already commented. So I'll critique your presentation: it's pretty bad. The browny-orange vignette you applied to the image is an odd colour and does anything but subtle. This photo also suffers from some rather extreme jpeg artifacts, something that you should be screening for before upload. What's the point of nice photo equipment if you turn the image into mush when displaying it?
Evening Mischivo, I just wanted to say that the colors you are seeing in the image are accurate - very accurate. The colors in the Canyon vary by the minute, and depend on the type of available lighting, weather condition, sky condition, direct sunlight or indirect. Also, where you might be standing and the angle you are viewing are all contributing factors. The colors range from the reds/oranges to the full range of browns, with the full gamut of all the earth tones. Purples and blues mixed with reds and oranges are also there - usually in the early mornings or late afternoons. Summer with the intense direct sunlight brings one set of tones, while winter and the clouds with snow brings another completely new set of color ranges. The colors may be vivid one minute and muted the next. If you want another completely different image, just wait a couple of minutes for a passing cloud or.....
Just an hour south in Sedona, brings another complete set of reds and deep oranges, that turn to a full range of pinks with the right sun. Sedona is world famous for its red rocks. Just a stone's throw away from the Grand Canyon is Antelope Canyon - a slot canyon with another completely different set of colors, in a 360 degree full surrounding view.
Some of the world's best photographers work for and contribute to Arizona Highways Magazine. Their pictures are absolutely spectacular across the Arizona landscapes. Every color imaginable is available, and is shown in the magazine.

I find when I shoot up there, its impossible to adjust the colors - so I don't. I might adjust the contrast and exposures a bit for the shadows, or bracket to get the full dynamic range, especially across the sun drenched areas as compared to the shadowed areas. The colors, I find - the best thing to do is just leave them alone since no one is going to believe them anyway - at least until they visit.
