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 #91cac2

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 #295650
Safe as a 1px border on white
No — use #4EA296

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.

Transparency

What each alpha value actually composites to. The top row is #91cac2 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.

#91cac2, answered

What color is #91cac2?

#91cac2 is a light soft cyan, closest to Medium Turquoise (ΔE2000 8.4). It sits at 172° on the hue wheel with 35% saturation and 68% lightness, which reads as cool.

What is the RGB value of #91cac2?

rgb(145, 202, 194) — 145 red, 202 green and 194 blue out of 255, or 56.9% / 79.2% / 76.1% by channel.

What is #91cac2 in HSL and HSV?

hsl(172, 35%, 68%) and hsv(172, 28%, 79%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #91cac2 a light or a dark color?

It is a light color. Relative luminance is 0.5216 and perceived brightness is 73%, so black text on it reaches 11.43:1.

Should I use black or white text on #91cac2?

Black. It scores 11.43:1 against #91cac2, versus 1.84:1 for white — AAA at any size.

Is #91cac2 accessible on a white background?

#91cac2 on white scores 1.84:1, which fails WCAG AA at every size. Darken it to #3D7F76 to reach 4.5:1, or #2E6059 for 7:1.

What is the complementary color of #91cac2?

#CA9199 sits directly opposite on the wheel. Softer options are the split-complements #CA91B5 and #CAA591, which give the same contrast with far less vibration.

What colors go well with #91cac2?

For interface work: #F5FAF9 as the surface, #C8E4E0 for borders, #4B9B90 for secondary text, #8D3F5D as an accent and #295650 for hover and pressed states. For a palette, the analogous pair #91CAA5 and #91B5CA stays calm, while #CA9199 is the loudest partner.

What is #91cac2 in CMYK for printing?

cmyk(28%, 0%, 4%, 21%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #91cac2 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 #91CAAD; nudged cooler, #8FBECC.

Which Tailwind color is closest to #91cac2?

The teal family — its 500 step is #14b8a6, ΔE2000 12 away. That is a visible difference, so define #91cac2 as a custom token rather than reaching for the built-in.

How do I use #91cac2 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#91cac2] or text-[#91cac2], 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 #91cac2 with 50% opacity?

rgba(145, 202, 194, 0.5), or #91cac280 in eight-digit hex. Over white that composites to #C8E5E1; over black, #496561.

Is #91cac2 a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 3.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #91cac2 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 #91cac2?

The safest is same-hue elevation: linear-gradient(135deg, #BADED9, #91cac2 45%, #295650). For more colour, a short hue run to #7C97C0 keeps it rich without turning muddy.
