Every value on this page is computed at build time from the hex code above using ChromaWell's shared, unit-tested color-core library — the same conversion, contrast, and nearest-name math used across every color page on this site, so a value here matches the same color looked up anywhere else on ChromaWell.

The conversions block gives you the same color in seven common formats (hex, RGB, HSL, HSV, CMYK, Lab, and OKLCH) so you can copy whichever your codebase or design tool expects. The contrast block applies the WCAG 2.x relative-luminance formula against several common backgrounds and reports whether text in this color would pass AA or AAA at normal and large text sizes. Shades/tints step the lightness up and down at a fixed hue and saturation; harmonies rotate the hue around the color wheel to surface complementary, analogous, triadic, and split-complementary partners; and nearest named colors ranks the closest matches from our full 1,094-color dataset by CIE76 Delta-E distance in Lab space, a perceptual distance metric rather than a raw RGB difference.

Conversions

HEX: #748B97
RGB: rgb(116, 139, 151)
HSL: hsl(200.6, 14.4%, 52.4%)

WCAG contrast

On white: 3.57:1 — normal text FAIL, large text AA
On black: 5.88:1 — normal text AA, large text AAA
On pure white: 3.57:1 — normal text FAIL, large text AA
On pure black: 5.88:1 — normal text AA, large text AAA
On light gray (#F3F4F6): 3.24:1 — normal text FAIL, large text AA
On dark slate (#1F2937): 4.11:1 — normal text FAIL, large text AA

Ratios computed from WCAG 2.x relative luminance; AA needs 4.5:1 for normal text and 3:1 for large text (18pt+ or 14pt+ bold), AAA needs 7:1 and 4.5:1 respectively.

Perceptual profile

Hue 200.6° places this color in the cool range of the wheel. At 14.4% saturation it reads as essentially neutral/gray, and at 52.4% lightness it sits at mid-tone. In OKLCH — the newer, perceptually uniform color space — this color's lightness is 0.6229, chroma 0.032, hue 230.6°, which is a more accurate predictor of how "bright" this color will look next to others than HSL lightness alone.

Use in CSS

This is a cool hue at 14.4% saturation and 52.4% lightness. Drop it into a stylesheet as a custom property:
