Electric Ultramarine
An aggressively saturated and electric indigo
Electric Ultramarine is an aggressively saturated indigo that demands attention. Because of its extreme intensity, it functions best as a focused accent or a bold call-to-action button rather than a primary background. It pairs surprisingly well with muted mustard yellows for a modern, high-contrast look. White text remains perfectly legible against this shade. The hex code for Electric Ultramarine is #3f00ff.
