Blue color values and uses
Blue is represented here by #0000FF. In digital artwork, websites, and interface design, HEX is a compact way to specify the exact red, green, and blue channels. The equivalent RGB value is rgb(0, 0, 255); HSL hsl(240, 100%, 50%) describes hue, saturation, and lightness, while CMYK 0%, 100%, 0%, 0% offers a starting point for print workflows. These conversions are useful when moving a color between design tools, though displays, printers, and color profiles can produce different results.
Use blue alongside the swatches above to compare lighter tints, deeper shades, and nearby hues. A restrained palette can reserve this color for a focal element and use a neutral background for supporting content. For text and controls, check contrast at the size and weight where the color will appear; a swatch that looks clear on a large area may be harder to read in small labels. Save the HEX or RGB value in your design system so the same color can be reused consistently.
