How to use #027f67

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

Works well for
  • Body text and links on white
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Full-page backgrounds — tiring over long sessions
  • Black text placed on it
  • Thin strokes and 1px borders — they disappear on light UI
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. 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 #027f67 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.

#027f67, answered

What color is #027f67?

#027f67 is a dark electric cyan, closest to Sea Green (ΔE2000 9.3). It sits at 169° on the hue wheel with 97% saturation and 25% lightness, which reads as cool.

What is the RGB value of #027f67?

rgb(2, 127, 103) — 2 red, 127 green and 103 blue out of 255, or 0.8% / 49.8% / 40.4% by channel.

What is #027f67 in HSL and HSV?

hsl(169, 97%, 25%) and hsv(168, 98%, 50%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #027f67 a light or a dark color?

It is a dark color. Relative luminance is 0.1617 and perceived brightness is 41%, so white text on it reaches 4.96:1.

Should I use black or white text on #027f67?

White. It scores 4.96:1 against #027f67, versus 4.23:1 for black — AA at any size.

Is #027f67 accessible on a white background?

#027f67 on white scores 4.96:1, which clears AA at every size but not AAA.

What is the complementary color of #027f67?

#7F021A sits directly opposite on the wheel. Softer options are the split-complements #7F0258 and #7F2902, which give the same contrast with far less vibration.

What colors go well with #027f67?

For interface work: #F4FAF9 as the surface, #C0EDE4 for borders, #4B9B8C for secondary text, #810039 as an accent and #027E66 for hover and pressed states. For a palette, the analogous pair #027F29 and #02587F stays calm, while #7F021A is the loudest partner.

What is #027f67 in CMYK for printing?

cmyk(98%, 0%, 19%, 50%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #027f67 warm or cool?

Cool — it scores 83 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #027F39; nudged cooler, #016A80.

Which Tailwind color is closest to #027f67?

The teal family — its 500 step is #14b8a6, ΔE2000 19.1 away. That is a visible difference, so define #027f67 as a custom token rather than reaching for the built-in.

How do I use #027f67 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#027f67] or text-[#027f67], 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 #027f67 with 50% opacity?

rgba(2, 127, 103, 0.5), or #027f6780 in eight-digit hex. Over white that composites to #81BFB3; over black, #014034.

Is #027f67 a web-safe color?
