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 #3ebaa7

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

Works well for
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #206056
Safe as a 1px border on white
No — use #36A392

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The mid lightness keeps it versatile in both themes.

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 #3ebaa7 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.

#3ebaa7, answered

What color is #3ebaa7?

#3ebaa7 is a balanced vivid cyan, closest to Light Sea Green (ΔE2000 4.6). It sits at 171° on the hue wheel with 50% saturation and 49% lightness, which reads as cool.

What is the RGB value of #3ebaa7?

rgb(62, 186, 167) — 62 red, 186 green and 167 blue out of 255, or 24.3% / 72.9% / 65.5% by channel.

What is #3ebaa7 in HSL and HSV?

hsl(171, 50%, 49%) and hsv(171, 67%, 73%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #3ebaa7 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3893 and perceived brightness is 62%, so black text on it reaches 8.79:1.

Should I use black or white text on #3ebaa7?

Black. It scores 8.79:1 against #3ebaa7, versus 2.39:1 for white — AAA at any size.

Is #3ebaa7 accessible on a white background?

#3ebaa7 on white scores 2.39:1, which fails WCAG AA at every size. Darken it to #2B8173 to reach 4.5:1, or #216258 for 7:1.

What is the complementary color of #3ebaa7?

#BA3E51 sits directly opposite on the wheel. Softer options are the split-complements #BA3E8F and #BA693E, which give the same contrast with far less vibration.

What colors go well with #3ebaa7?

For interface work: #F4FAF9 as the surface, #C2EBE4 for borders, #4B9B8F for secondary text, #BF396F as an accent and #206056 for hover and pressed states. For a palette, the analogous pair #3EBA69 and #3E8FBA stays calm, while #BA3E51 is the loudest partner.

What is #3ebaa7 in CMYK for printing?

cmyk(67%, 0%, 10%, 27%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #3ebaa7 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 #3EBA79; nudged cooler, #3BA1BC.

Which Tailwind color is closest to #3ebaa7?

The teal family — its 500 step is #14b8a6, ΔE2000 1.9 away. That is close enough to swap in without anyone noticing.

How do I use #3ebaa7 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#3ebaa7] or text-[#3ebaa7], 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 #3ebaa7 with 50% opacity?

rgba(62, 186, 167, 0.5), or #3ebaa780 in eight-digit hex. Over white that composites to #9FDDD3; over black, #1F5D54.

Is #3ebaa7 a web-safe color?

No. The nearest web-safe colour is #33CC99, ΔE2000 9.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #3ebaa7 mean?

As a cyan, it reads clean, technical, fresh. Cyan reads as water, air and infrastructure: cool, hygienic, engineered. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #3ebaa7?

The safest is same-hue elevation: linear-gradient(135deg, #68CDBD, #3ebaa7 45%, #206056). For more colour, a short hue run to #3662A3 keeps it rich without turning muddy.
