#287ACC Hex Color

#287acc reads as a cool blue because its hue leans slightly toward cyan, while its fairly high saturation keeps the color clear rather than muted across screens and printed surfaces. Its medium-dark value gives interfaces a controlled, dependable feel without the weight of navy.

For clean layouts, #287acc pairs well with warm off-white, while terracotta adds energy and charcoal anchors supporting text or panels without competing with its cool, fairly saturated blue character on screen.

#287acc supports black body text at about 4.7:1 contrast, which clears the WCAG AA 4.5:1 threshold for normal text; verify the final pairing when using white text, small type, or antialiased interface labels.
