#052DBE

sRGB: 5 / 45 / 190

#052DBE belongs to the blue family. Its hex code tells a screen to mix 5 red, 45 green and 190 blue on a scale of 0 to 255. On the HSL wheel, hue is a position around a circle: 227.0° lands in the blue region. Its 94.9% saturation makes it strong in color at this lightness. HSL lightness is 38.2% on a scale from black (0%) to white (100%). Of black and white lettering, white has the clearer light-to-dark separation on this background (9.88:1), which helps the shapes of letters stand out.

Text contrast

Contrast tells you how clearly lettering separates from #052DBE in light and dark. The ratio compares relative luminance, a measure of light weighted for human vision. Identical colors give 1:1 and black against white gives 21:1. A ratio of 2.99:1 falls just below the 3:1 AA minimum for large text. Body text needs at least 4.5:1 because its finer strokes are harder to distinguish.

Black text: 2.13:1

Normal text: Fail
Large text: Fail

White text: 9.88:1

Normal text: AAA
Large text: AAA

AA and AAA are WCAG accessibility levels. AAA sets a higher bar: 7:1 for normal text and 4.5:1 for large text. Large text begins at 18 pt regular or 14 pt bold. Ratings use the unrounded ratio.

Palettes & scales

Harmonies rotate the hue. Scales mix the starting color with white, black or middle gray in 20% steps in encoded sRGB.

Complementary

#BE9605 sits half a turn (180°) from #052DBE on the HSL wheel. Keeping saturation and lightness steady while crossing to the opposite hue gives you a contrasting accent. Check text contrast separately before using the pair for lettering.

#052DBE #BE9605

Analogous

#0589BE and #3A05BE sit 30° to either side of #052DBE. The three hues are neighbors on the wheel, so you can change the color of a border or highlight while keeping it close to the original.

#0589BE #052DBE #3A05BE

Triadic

#052DBE, #BE052D and #2DBE05 are spaced 120° apart, forming a triangle on the wheel. Try one for the main color and the other two for accents.
