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 #5ebaaf

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 #265953
Safe as a 1px border on white
No — use #45A095

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.

#5ebaaf, answered

What color is #5ebaaf?

#5ebaaf is a balanced soft cyan, closest to Light Sea Green (ΔE2000 4.8). It sits at 173° on the hue wheel with 40% saturation and 55% lightness, which reads as cool.

What is the RGB value of #5ebaaf?

rgb(94, 186, 175) — 94 red, 186 green and 175 blue out of 255, or 36.9% / 72.9% / 68.6% by channel.

What is #5ebaaf in HSL and HSV?

hsl(173, 40%, 55%) and hsv(173, 49%, 73%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #5ebaaf a light or a dark color?

It is a mid-tone. Relative luminance is 0.4059 and perceived brightness is 64%, so black text on it reaches 9.12:1.

Should I use black or white text on #5ebaaf?

Black. It scores 9.12:1 against #5ebaaf, versus 2.30:1 for white — AAA at any size.

Is #5ebaaf accessible on a white background?

#5ebaaf on white scores 2.30:1, which fails WCAG AA at every size. Darken it to #378077 to reach 4.5:1, or #296059 for 7:1.

What is the complementary color of #5ebaaf?

#BA5E69 sits directly opposite on the wheel. Softer options are the split-complements #BA5E97 and #BA815E, which give the same contrast with far less vibration.

What colors go well with #5ebaaf?

For interface work: #F4FAFA as the surface, #C6E7E3 for borders, #4B9B91 for secondary text, #BF597F as an accent and #265953 for hover and pressed states. For a palette, the analogous pair #5EBA81 and #5E97BA stays calm, while #BA5E69 is the loudest partner.

What is #5ebaaf in CMYK for printing?

cmyk(50%, 0%, 6%, 27%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #5ebaaf 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 #5EBA8D; nudged cooler, #5CA4BC.

Which Tailwind color is closest to #5ebaaf?

The teal family — its 500 step is #14b8a6, ΔE2000 5.1 away. That is a visible difference, so define #5ebaaf as a custom token rather than reaching for the built-in.

How do I use #5ebaaf in Tailwind CSS?

Inline it as an arbitrary value with bg-[#5ebaaf] or text-[#5ebaaf], 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 #5ebaaf with 50% opacity?

rgba(94, 186, 175, 0.5), or #5ebaaf80 in eight-digit hex. Over white that composites to #AFDDD7; over black, #2F5D58.

Is #5ebaaf a web-safe color?

No. The nearest web-safe colour is #66CC99, ΔE2000 12.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #5ebaaf 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 #5ebaaf?

The safest is same-hue elevation: linear-gradient(135deg, #89CCC4, #5ebaaf 45%, #265953). For more colour, a short hue run to #4B70AF keeps it rich without turning muddy.
