#135bf7 is a loud, electric blue with real presence. Its saturation is the whole story: this is a color that refuses to sit quietly, which makes it a natural pick for calls to action, active states, and brand moments that need attention. Designers get the best results when they let it dominate. It holds up as a dominant base for buttons and large type, flatters white text at nearly full contrast, and reads as confident rather than cold. Pair it with warm coral or amber accents to keep it from feeling corporate.
