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 #4daba4

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 #285854
Safe as a 1px border on white
No — use #48A09A

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.

What each alpha value actually composites to. The top row is #4daba4 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.

#4daba4, answered

What color is #4daba4?

#4daba4 is a balanced soft cyan, closest to Light Sea Green (ΔE2000 3.5). It sits at 176° on the hue wheel with 38% saturation and 49% lightness, which reads as cool.

What is the RGB value of #4daba4?

rgb(77, 171, 164) — 77 red, 171 green and 164 blue out of 255, or 30.2% / 67.1% / 64.3% by channel.

What is #4daba4 in HSL and HSV?

hsl(176, 38%, 49%) and hsv(176, 55%, 67%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #4daba4 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3338 and perceived brightness is 58%, so black text on it reaches 7.68:1.

Should I use black or white text on #4daba4?

Black. It scores 7.68:1 against #4daba4, versus 2.74:1 for white — AAA at any size.

Is #4daba4 accessible on a white background?

#4daba4 on white scores 2.74:1, which fails WCAG AA at every size. Darken it to #3A817B to reach 4.5:1, or #2C615D for 7:1.

What is the complementary color of #4daba4?

#AB4D54 sits directly opposite on the wheel. Softer options are the split-complements #AB4D83 and #AB754D, which give the same contrast with far less vibration.

What colors go well with #4daba4?

For interface work: #F4FAFA as the surface, #C7E6E3 for borders, #4B9B95 for secondary text, #B0486A as an accent and #285854 for hover and pressed states. For a palette, the analogous pair #4DAB75 and #4D83AB stays calm, while #AB4D54 is the loudest partner.

What is #4daba4 in CMYK for printing?

cmyk(55%, 0%, 4%, 33%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #4daba4 warm or cool?

Cool — it scores 86 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #4DAB81; nudged cooler, #4A91AD.

Which Tailwind color is closest to #4daba4?

The teal family — its 500 step is #14b8a6, ΔE2000 6 away. That is a visible difference, so define #4daba4 as a custom token rather than reaching for the built-in.

How do I use #4daba4 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#4daba4] or text-[#4daba4], 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 #4daba4 with 50% opacity?

rgba(77, 171, 164, 0.5), or #4daba480 in eight-digit hex. Over white that composites to #A6D5D2; over black, #275652.

Is #4daba4 a web-safe color?

No. The nearest web-safe colour is #669999, ΔE2000 7.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #4daba4 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 #4daba4?

The safest is same-hue elevation: linear-gradient(135deg, #74C1BB, #4daba4 45%, #285854). For more colour, a short hue run to #435E96 keeps it rich without turning muddy.
