Getting color right in red rock country is very challenging because you have no neutral reference to work from to assess the color of your light that is falling on your red/brown.
The color of the light that is illuminating your clouds and generating all those wonderful colors is a different color of light from the cyan/blue overhead sky that is illuminating your foreground. While I still would treat the colors of light independently, I can pretty much figure on the one cloud @ neutral, but the foreground is @ assessing.
I rarely use my gray card, but this is an area where a gray card might come in handy since nature is not providing you a known/assumed neutral in the foreground. We tend to trust our clouds as being a WB reference, but in dramatic lighting such as this where our clouds and foreground aren't being illuminated by the same color/source, the cloud isn't much help for the WB @ foreground. I gave it some more tweaks on color to bring it back down to earth a bit (sorry Steve ), but I'm still guessing without a foreground neutral reference in the scene.
If you can go back to the location, you could shoot a foreground gray card at same time of day to help assess the color as a reference point for your work on this one. I'm sure mine is still "not right", but hopefully this still gives a gist @ some variants for dialing it in to where you want it. It would be interesting to see the pre-pp version and work from there, if you are so inclined to see what others might take for their approach.
Here's another piece of the puzzle that comes into play. While the color of the light is different, the quality of the light is different also. The foreground is illuminated with soft lighting while the clouds are illuminated with more specular light. I tend to think that this is in part what gives the HDR look when raising the underexposed, softer foreground areas. This is probably where working from two properly exposed images has value worth the extra effort.
BTW, the title says twilight, and the file info says the image was shot @ 10:00 AM. Time of day/directional orientation of the day impacts what color our light is. In my assessment of the lighting to generate the colors in the clouds, the sun would need to be either below or to the side of the clouds such that the warm direct sunlight isn't shining "down" much onto the ground, but rather up/into the clouds. 10:00 AM seems like an odd time for this to be happening, but also I was confused as to whether presentation should be more twilight-ish or daylight-ish.
Just some @ food for thought as you work to get it where you want it. Still a very nice capture that I'm sure was excellent to enjoy both in person and shooting it. Be patient with your processing as you've got a fine piece here that deserves some judicious attention to bring it to its fullest. These small jpg reworks are something I consider more as a brainstorming sketch/draft for direction rather than a finished product. HTH.
