From a colour-veil perspective (art therapy) this is an excellent example of ("pale") indigo! It is actually a dark colour with little luminosity, so here it is the darkness around the highlights. When the indigo is too intense it gets hot, otherwise, when it is too pale it lacks warmth. It can then easily have an eerie feel to it, like some volcanic landscapes in the moonlight. Good to see a hyper modern example of such a scape.
