On my most recent trip to Luxor, I went to visit my favorite spot in Medinat Habu (Habu Temple). I was surprised to see scaffolding on a large section of the columns, with a team of young students working diligently on it. 

I must admit, I liked the idea of removing dust, dirt, bird poop, etc. However, when I realized that the colorful sections were changing color, I was a bit concerned.

As a purist, I much prefer the 'weathered by thousands of years' look, but I am hopeful that this deepening of the colors will lighten over the coming months.

I'll find out soon on my next visit!
