Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.

How to use #6abeb3

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 #275952
Safe as a 1px border on white
No — use #47A397

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.

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.

#6abeb3, answered

What color is #6abeb3?

#6abeb3 is a balanced soft cyan, closest to Medium Turquoise (ΔE2000 6.3). It sits at 172° on the hue wheel with 39% saturation and 58% lightness, which reads as cool.

What is the RGB value of #6abeb3?

rgb(106, 190, 179) — 106 red, 190 green and 179 blue out of 255, or 41.6% / 74.5% / 70.2% by channel.

What is #6abeb3 in HSL and HSV?

hsl(172, 39%, 58%) and hsv(172, 44%, 75%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #6abeb3 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4315 and perceived brightness is 66%, so black text on it reaches 9.63:1.

Should I use black or white text on #6abeb3?

Black. It scores 9.63:1 against #6abeb3, versus 2.18:1 for white — AAA at any size.

Is #6abeb3 accessible on a white background?

#6abeb3 on white scores 2.18:1, which fails WCAG AA at every size. Darken it to #388076 to reach 4.5:1, or #2A6059 for 7:1.

What is the complementary color of #6abeb3?

#BE6A75 sits directly opposite on the wheel. Softer options are the split-complements #BE6A9F and #BE896A, which give the same contrast with far less vibration.

What colors go well with #6abeb3?

For interface work: #F4FAFA as the surface, #C6E6E2 for borders, #4B9B90 for secondary text, #C26689 as an accent and #275952 for hover and pressed states. For a palette, the analogous pair #6ABE89 and #6A9FBE stays calm, while #BE6A75 is the loudest partner.

What is #6abeb3 in CMYK for printing?

cmyk(44%, 0%, 6%, 26%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #6abeb3 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 #6ABE94; nudged cooler, #68ABC0.

Which Tailwind color is closest to #6abeb3?

The teal family — its 500 step is #14b8a6, ΔE2000 6.4 away. That is a visible difference, so define #6abeb3 as a custom token rather than reaching for the built-in.

How do I use #6abeb3 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#6abeb3] or text-[#6abeb3], 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 #6abeb3 with 50% opacity?

rgba(106, 190, 179, 0.5), or #6abeb380 in eight-digit hex. Over white that composites to #B5DFD9; over black, #355F5A.

Is #6abeb3 a web-safe color?

No. The nearest web-safe colour is #66CCCC, ΔE2000 5.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #6abeb3 mean?

As a cyan, it reads clean, technical, fresh. Cyan reads as water, air and infrastructure: cool, hygienic, engineered. At this moderate chroma the association is present but not shouted.

What gradient works with #6abeb3?

The safest is same-hue elevation: linear-gradient(135deg, #94D1C9, #6abeb3 45%, #275952). For more colour, a short hue run to #5479B5 keeps it rich without turning muddy.
