One of the more visually exciting parts of Hanoi is the colors of the streets at night. The Old Quarter of Hanoi is a walking part of the city for the most part. Shops stay open until close to 8:00 pm. This makes for many people and scooters still very active in brightly light streets.
The range of light colors come from the many different types of lights used in the shops and streets. Fluorescent, LED and incandescent all have a unique color temperature look in the camera.
