I cannot see the image, but I suppose it's the same that has been discussed here before, for example in
As I said in those previous discussions, I don't think this is a doorway, just a slightly recessed space.
The colours are not real, the image is made with infrared, red and green+blue (the filters available on the camera aboard Mars Reconnaissance Orbiter)
instead of red, green and blue.
The image can be seen here
in its original size, a huge 4048 x 50000 pixels image.
As all HiRISE images are JPEG 2000 you have to use a program that can handle that file format. I use IAS Viewer, just follow the instructions
Edit: I see the image now, it's the one I was expecting.
