Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

neutralquieteditorialengineered

Grey is the material the rest of the interface is built from: type, rules, surfaces, disabled states.

With almost no chroma left, the family association is barely present; treat it as a neutral that happens to lean this way. The low lightness adds weight and formality.

Worth knowing

Mid-greys are where accessibility quietly fails — check every step of your ladder, not just the ends.

What each alpha value actually composites to. The top row is #6c6471 over white; the bottom row is the same alpha over a checkerboard, so you can see what survives on a photo or a video.

Bottom row of hexes is the flattened result over white — use those when a design tool refuses transparency, or when you need a solid fallback.

#6c6471, answered

What color is #6c6471?

#6c6471 is a dark muted gray, closest to Dim Gray (ΔE2000 8.7). It sits at 277° on the hue wheel with 6% saturation and 42% lightness, which reads as neutral.

What is the RGB value of #6c6471?

rgb(108, 100, 113) — 108 red, 100 green and 113 blue out of 255, or 42.4% / 39.2% / 44.3% by channel.

What is #6c6471 in HSL and HSV?

hsl(277, 6%, 42%) and hsv(277, 12%, 44%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #6c6471 a light or a dark color?

It is a dark color. Relative luminance is 0.1349 and perceived brightness is 41%, so white text on it reaches 5.68:1.

Should I use black or white text on #6c6471?

White. It scores 5.68:1 against #6c6471, versus 3.70:1 for black — AA at any size.

Is #6c6471 accessible on a white background?

#6c6471 on white scores 5.68:1, which clears AA at every size but not AAA.

What is the complementary color of #6c6471?

#697164 sits directly opposite on the wheel. Softer options are the split-complements #707164 and #647166, which give the same contrast with far less vibration.

What colors go well with #6c6471?

For interface work: #F7F7F8 as the surface, #D7D4D9 for borders, #746C7A for secondary text, #6D7560 as an accent and #413C44 for hover and pressed states. For a palette, the analogous pair #666471 and #716470 stays calm, while #697164 is the loudest partner.

What is #6c6471 in CMYK for printing?

cmyk(4%, 12%, 0%, 56%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #6c6471 warm or cool?

Neutral — it scores 52 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #7F6E60; nudged cooler, #576574.

Which Tailwind color is closest to #6c6471?

The zinc family — its 500 step is #71717a, ΔE2000 6.4 away. That is a visible difference, so define #6c6471 as a custom token rather than reaching for the built-in.

How do I use #6c6471 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#6c6471] or text-[#6c6471], or register the whole ramp under theme.extend.colors.brand so you get bg-brand-500 and friends. The generated 50–950 scale on this page is ready to paste into your config.

What is #6c6471 with 50% opacity?

rgba(108, 100, 113, 0.5), or #6c647180 in eight-digit hex. Over white that composites to #B6B2B8; over black, #363239.

Is #6c6471 a web-safe color?
