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 #abc1bc

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

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • White 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
Not as text
Safe as a fill behind white type
No — use #364945
Safe as a 1px border on white
No — use #799C94

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 lightness keeps it airy and approachable.

Worth knowing

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

#abc1bc, answered

What color is #abc1bc?

#abc1bc is a light soft cyan, closest to Silver (ΔE2000 9.9). It sits at 166° on the hue wheel with 15% saturation and 71% lightness, which reads as cool.

What is the RGB value of #abc1bc?

rgb(171, 193, 188) — 171 red, 193 green and 188 blue out of 255, or 67.1% / 75.7% / 73.7% by channel.

What is #abc1bc in HSL and HSV?

hsl(166, 15%, 71%) and hsv(166, 11%, 76%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #abc1bc a light or a dark color?

It is a light color. Relative luminance is 0.5043 and perceived brightness is 73%, so black text on it reaches 11.09:1.

Should I use black or white text on #abc1bc?

Black. It scores 11.09:1 against #abc1bc, versus 1.89:1 for white — AAA at any size.

Is #abc1bc accessible on a white background?

#abc1bc on white scores 1.89:1, which fails WCAG AA at every size. Darken it to #5C7C75 to reach 4.5:1, or #445C57 for 7:1.

What is the complementary color of #abc1bc?

#C1ABB0 sits directly opposite on the wheel. Softer options are the split-complements #C1ABBB and #C1B1AB, which give the same contrast with far less vibration.

What colors go well with #abc1bc?

For interface work: #F6F9F8 as the surface, #D0DCDA for borders, #61847C for secondary text, #7A5265 as an accent and #364945 for hover and pressed states. For a palette, the analogous pair #ABC1B1 and #ABBBC1 stays calm, while #C1ABB0 is the loudest partner.

What is #abc1bc in CMYK for printing?

cmyk(11%, 0%, 3%, 24%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #abc1bc warm or cool?

Cool — it scores 64 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #ABC1B4; nudged cooler, #AABFC3.

Which Tailwind color is closest to #abc1bc?

The teal family — its 500 step is #14b8a6, ΔE2000 18 away. That is a visible difference, so define #abc1bc as a custom token rather than reaching for the built-in.

How do I use #abc1bc in Tailwind CSS?

Inline it as an arbitrary value with bg-[#abc1bc] or text-[#abc1bc], 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 #abc1bc with 50% opacity?

rgba(171, 193, 188, 0.5), or #abc1bc80 in eight-digit hex. Over white that composites to #D5E0DE; over black, #56615E.

Is #abc1bc a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 7.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #abc1bc 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 #abc1bc?

The safest is same-hue elevation: linear-gradient(135deg, #CEDBD8, #abc1bc 45%, #364945). For more colour, a short hue run to #99A6B4 keeps it rich without turning muddy.
