Inspired by the soft daylight and sea breezes of Istanbul, this theme blends calm turquoise tones with warm historical accents to create a serene yet expressive coding environment. Light, airy backgrounds keep the editor clean and comfortable, while teals, aquas, and muted golden hues add clarity and focus to essential syntax elements.
