How to use #67a2ab

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

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Thin strokes and 1px borders — they disappear on light UI
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
Not as text
Safe as a fill behind white type
No — use #2D4D52
Safe as a 1px border on white
No — use #609EA7

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 mid lightness keeps it versatile in both themes.

Worth knowing

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

#67a2ab, answered

What color is #67a2ab?

#67a2ab is a balanced soft cyan, closest to Cadet Blue (ΔE2000 3.7). It sits at 188° on the hue wheel with 29% saturation and 54% lightness, which reads as cool.

What is the RGB value of #67a2ab?

rgb(103, 162, 171) — 103 red, 162 green and 171 blue out of 255, or 40.4% / 63.5% / 67.1% by channel.

What is #67a2ab in HSL and HSV?

hsl(188, 29%, 54%) and hsv(188, 40%, 67%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #67a2ab a light or a dark color?

It is a mid-tone. Relative luminance is 0.3166 and perceived brightness is 58%, so black text on it reaches 7.33:1.

Should I use black or white text on #67a2ab?

Black. It scores 7.33:1 against #67a2ab, versus 2.86:1 for white — AAA at any size.

Is #67a2ab accessible on a white background?

#67a2ab on white scores 2.86:1, which fails WCAG AA at every size. Darken it to #4A7E86 to reach 4.5:1, or #385F65 for 7:1.

What is the complementary color of #67a2ab?

#AB7067 sits directly opposite on the wheel. Softer options are the split-complements #AB6780 and #AB9267, which give the same contrast with far less vibration.

What colors go well with #67a2ab?

For interface work: #F5F9FA as the surface, #CADFE2 for borders, #528B94 for secondary text, #B0626B as an accent and #2D4D52 for hover and pressed states. For a palette, the analogous pair #67AB92 and #6780AB stays calm, while #AB7067 is the loudest partner.

What is #67a2ab in CMYK for printing?

cmyk(40%, 5%, 0%, 33%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #67a2ab 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 #67AB9B; nudged cooler, #658EAD.

Which Tailwind color is closest to #67a2ab?

The cyan family — its 500 step is #06b6d4, ΔE2000 9.4 away. That is a visible difference, so define #67a2ab as a custom token rather than reaching for the built-in.

How do I use #67a2ab in Tailwind CSS?

Inline it as an arbitrary value with bg-[#67a2ab] or text-[#67a2ab], 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 #67a2ab with 50% opacity?

rgba(103, 162, 171, 0.5), or #67a2ab80 in eight-digit hex. Over white that composites to #B3D1D5; over black, #345156.

Is #67a2ab a web-safe color?

No. The nearest web-safe colour is #669999, ΔE2000 4.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #67a2ab mean?
