Cornflower Blue#6495ED, a cool brilliant blue

At a glanceCornflower Blue is #6495ED, oklch(67.5% 0.141 261.3), a cool brilliant blue, also known as cornflowerblue or Guilliman Blue. Partner it with a warm medium scarlet #D7745A as an accent, a cool light turquoise #71B8D6 for harmony, and a cool muted blue #707886 as a neutral. Put it to work as a screen-first brand or accent color, and it takes black text at AA contrast. It shifts further on press than a run can hold, though, so Rhapsody would keep it off print-led brand work.

Color family

What kind of blue is Cornflower Blue?

Every color has a place in the standard vocabulary. This is Cornflower Blue's, measured rather than asserted.
