bboyminn:

Some snakes have a sense or type of night vision. Their visual
spectrum extends down into the infrared range and this allows 
them to track small creatures like mice through dense grass 
and underbrush.

This infrared vision is indicated in Nagini's case in the line-

'...he could see objects around him shimmering in strange, 
vibrant colors.' 

If you have ever seen thermal or infrared sensing equipment,
heat or infrared shows up as a gradient of colors. 

This infrared quality also gives snake good night vision. 

So, to a degree, yes, Nagini could see Arthur even in a dark
hallway, and yes, since the snake is detecting infrared, she
could see him under the Cloak.
