  • Brand accents, badges and data highlights
Use with care
  • Black text placed on it
  • Thin strokes and 1px borders — they disappear on light UI
  • Pairing with a same-lightness hue — edges vibrate

Meaning and mood

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

cleantechnicalfreshclinical

Cyan reads as water, air and infrastructure: cool, hygienic, engineered.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. The low lightness adds weight and formality.

Worth knowing

At high lightness it disappears into white surfaces and thin strokes vanish entirely.

Transparency

What each alpha value actually composites to. The top row is #476973 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.

#476973, answered

What color is #476973?

#476973 is a dark soft cyan, closest to Dark Slate Gray (ΔE2000 10.6). It sits at 194° on the hue wheel with 24% saturation and 37% lightness, which reads as cool.

What is the RGB value of #476973?

rgb(71, 105, 115) — 71 red, 105 green and 115 blue out of 255, or 27.8% / 41.2% / 45.1% by channel.

What is #476973 in HSL and HSV?

hsl(194, 24%, 37%) and hsv(194, 38%, 45%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #476973 a light or a dark color?

It is a dark color. Relative luminance is 0.1268 and perceived brightness is 38%, so white text on it reaches 5.94:1.

Should I use black or white text on #476973?

White. It scores 5.94:1 against #476973, versus 3.54:1 for black — AA at any size.

Is #476973 accessible on a white background?

#476973 on white scores 5.94:1, which clears AA at every size but not AAA.

What is the complementary color of #476973?

#735147 sits directly opposite on the wheel. Softer options are the split-complements #734753 and #736747, which give the same contrast with far less vibration.

What colors go well with #476973?

For interface work: #F6F8F9 as the surface, #CDDBE0 for borders, #58828E for secondary text, #774344 as an accent and #31484F for hover and pressed states. For a palette, the analogous pair #477367 and #475373 stays calm, while #735147 is the loudest partner.

What is #476973 in CMYK for printing?

cmyk(38%, 9%, 0%, 55%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #476973 warm or cool?

Cool — it scores 79 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #47736D; nudged cooler, #455E75.

Which Tailwind color is closest to #476973?

The slate family — its 500 step is #64748b, ΔE2000 11.8 away. That is a visible difference, so define #476973 as a custom token rather than reaching for the built-in.

How do I use #476973 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#476973] or text-[#476973], 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 #476973 with 50% opacity?

rgba(71, 105, 115, 0.5), or #47697380 in eight-digit hex. Over white that composites to #A3B4B9; over black, #24353A.
