How to use #39706f

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Body text and links on white
  • Charts, tags and secondary surfaces
  • Headers, footers and dark-mode surfaces
  • 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.

  • EnergyMedium
  • Weight67/100

Transparency

What each alpha value actually composites to. The top row is #39706f 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.

#39706f, answered

What color is #39706f?

#39706f is a dark soft cyan, closest to Teal (ΔE2000 7.1). It sits at 179° on the hue wheel with 33% saturation and 33% lightness, which reads as cool.

What is the RGB value of #39706f?

rgb(57, 112, 111) — 57 red, 112 green and 111 blue out of 255, or 22.4% / 43.9% / 43.5% by channel.

What is #39706f in HSL and HSV?

hsl(179, 33%, 33%) and hsv(179, 49%, 44%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #39706f a light or a dark color?

It is a dark color. Relative luminance is 0.1361 and perceived brightness is 39%, so white text on it reaches 5.64:1.

Should I use black or white text on #39706f?

White. It scores 5.64:1 against #39706f, versus 3.72:1 for black — AA at any size.

Is #39706f accessible on a white background?

#39706f on white scores 5.64:1, which clears AA at every size but not AAA.

What is the complementary color of #39706f?

#70393A sits directly opposite on the wheel. Softer options are the split-complements #703955 and #705339, which give the same contrast with far less vibration.

What colors go well with #39706f?

For interface work: #F5FAFA as the surface, #C9E3E3 for borders, #4D9897 for secondary text, #733646 as an accent and #2B5454 for hover and pressed states. For a palette, the analogous pair #397053 and #395570 stays calm, while #70393A is the loudest partner.

What is #39706f in CMYK for printing?

cmyk(49%, 0%, 1%, 56%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #39706f warm or cool?

Cool — it scores 84 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #39705B; nudged cooler, #375D72.

Which Tailwind color is closest to #39706f?

The neutral family — its 500 step is #737373, ΔE2000 17.7 away. That is a visible difference, so define #39706f as a custom token rather than reaching for the built-in.

How do I use #39706f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#39706f] or text-[#39706f], 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 #39706f with 50% opacity?

rgba(57, 112, 111, 0.5), or #39706f80 in eight-digit hex. Over white that composites to #9CB8B7; over black, #1D3838.

Is #39706f a web-safe color?
