Inspired by the Arctic night sky and the slow drift of the Northern Lights, this theme blends deep navy and teal shadows with luminous blue and green accents to create a calm yet vivid coding environment. Dark, cool backgrounds keep the editor restful, while bright cyans, fresh greens, and soft lavenders add clarity and energy to key syntax elements.
