Under an overcast sky, Montego blue is rather muted in tone, something like a navy blue. With bright sunshine, Montego blue is a bright blue. At night, it can take on an indigo tint. The type of lamps in the street lights affect that.
Here are a couple pictures I took of my E92 well after sundown. My digital camera was on a tripod so a long exposure would be possible.
The sky was clear. Sunset was about 9:00 PM, but had already sank below the hills surrounding this neighborhood before then. Artificial light was from a very tall yellow/green street light that was out of view well to the left of the camera. Reflected light from a few houses was unwanted, but what can you do in town?
