Nothing pastel here. #3f42c1 is a saturated indigo with a bold, electric feel that still reads dark and moody. Its purple undertone sits deeper than royal blue, so it flatters warm golds instead of the usual cool grays. Use it as a base for night sky themes or as an accent on dark interfaces. White text passes easily against this hex code, so labels and CTAs stay readable.
