#5C64BC Hex Color

#5c64bc looks best when balanced against high-contrast neutrals like crisp whites or a deep charcoal to anchor the design. For a more sophisticated palette, try introducing a soft, muted peach to provide a warm counterpoint to the cool, unsaturated tones of the indigo.

It serves as a strong, secondary accent color rather than a primary button shade because its restrained, unsaturated nature can feel too quiet for primary calls to action. Use it to build structure in layouts without overwhelming the user or competing with critical information.
