The sand should be orange! Why isn't the sand orange?

Most of the exterior desert scenes look so. fucking. boring. These scenes are so devoid of color because they were shot in the most beige landscape imaginable. The sand is white, the sky is white, Timothée Chalamet is white. There is no saturation, no contrast. It looks so dull and flat and lifeless.

The landscapes themselves look pretty cool but imagine how much cooler they'd look with even a little bit of color instead of this shit:

It's especially confusing because many of the other scenes in the film make excellent use of the monochromatic color scheme. The interior and nighttime shots have this stunning contrast with predominantly vibrant yellow-orange hues which really stand out. So having orange sand would have visually tied the whole film together. But instead we're stuck with beige for the majority of Part 2.

I had assumed they shot where they did due to logistical restrictions (it probably wouldn't have been practical to shoot in the Sahara desert) but I looked up Wadi Rum, the desert in Jordan where they filmed, and it's orange as hell!

This place looks like fucking Mars, so how did they mess this up? They found the most boring section in the whole desert and filmed there instead?

My best explanation is that this was a very intentional and deliberate choice, so that when the film actually does use color it's more impactful. But... I still don't like it, I think it sucks. The sand should be orange.
