#6477A0 Hex Color

Costume Blue pairs well with warm off-white for soft contrast and muted copper for restrained warmth, while charcoal adds a grounded dark accent without competing with its dusty undertones in layouts.

#6477a0 reads as a cool blue because its blue channel is stronger than its red and green channels, while gray undertones soften the hue and keep it from feeling bright or icy.

#6477a0 gives white text roughly a 6.7:1 contrast ratio, which generally passes WCAG AA for normal text; black text is only about 3.1:1, so avoid it for small body copy on this background.
