  • 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 #4f7675 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.

#4f7675, answered

What color is #4f7675?

#4f7675 is a dark soft cyan, closest to Teal (ΔE2000 8.7). It sits at 179° on the hue wheel with 20% saturation and 39% lightness, which reads as cool.

What is the RGB value of #4f7675?

rgb(79, 118, 117) — 79 red, 118 green and 117 blue out of 255, or 31% / 46.3% / 45.9% by channel.

What is #4f7675 in HSL and HSV?

hsl(179, 20%, 39%) and hsv(178, 33%, 46%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #4f7675 a light or a dark color?

It is a dark color. Relative luminance is 0.1590 and perceived brightness is 42%, so white text on it reaches 5.02:1.

Should I use black or white text on #4f7675?

White. It scores 5.02:1 against #4f7675, versus 4.18:1 for black — AA at any size.

Is #4f7675 accessible on a white background?

#4f7675 on white scores 5.02:1, which clears AA at every size but not AAA.

What is the complementary color of #4f7675?

#764F50 sits directly opposite on the wheel. Softer options are the split-complements #764F63 and #76614F, which give the same contrast with far less vibration.

What colors go well with #4f7675?

For interface work: #F6F9F9 as the surface, #CEDEDE for borders, #5C8988 for secondary text, #7A4B58 as an accent and #334C4C for hover and pressed states. For a palette, the analogous pair #4F7661 and #4F6376 stays calm, while #764F50 is the loudest partner.

What is #4f7675 in CMYK for printing?

cmyk(33%, 0%, 1%, 54%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #4f7675 warm or cool?

Cool — it scores 71 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #4F7667; nudged cooler, #4D6978.

Which Tailwind color is closest to #4f7675?

The neutral family — its 500 step is #737373, ΔE2000 14.4 away. That is a visible difference, so define #4f7675 as a custom token rather than reaching for the built-in.

How do I use #4f7675 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#4f7675] or text-[#4f7675], 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 #4f7675 with 50% opacity?

rgba(79, 118, 117, 0.5), or #4f767580 in eight-digit hex. Over white that composites to #A7BBBA; over black, #283B3B.

Is #4f7675 a web-safe color?

No. The nearest web-safe colour is #666666, ΔE2000 14.7 away. The palette only matters for legacy displays and some email clients now.
