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 #1ce2ac

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 #0E7156
Safe as a 1px border on white
No — use #15A77F

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. 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 #1ce2ac 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.

#1ce2ac, answered

What color is #1ce2ac?

#1ce2ac is a balanced electric cyan, closest to Medium Aqua Marine (ΔE2000 7.1). It sits at 164° on the hue wheel with 78% saturation and 50% lightness, which reads as cool.

What is the RGB value of #1ce2ac?

rgb(28, 226, 172) — 28 red, 226 green and 172 blue out of 255, or 11% / 88.6% / 67.5% by channel.

What is #1ce2ac in HSL and HSV?

hsl(164, 78%, 50%) and hsv(164, 88%, 89%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #1ce2ac a light or a dark color?

It is a light color. Relative luminance is 0.5762 and perceived brightness is 72%, so black text on it reaches 12.52:1.

Should I use black or white text on #1ce2ac?

Black. It scores 12.52:1 against #1ce2ac, versus 1.68:1 for white — AAA at any size.

Is #1ce2ac accessible on a white background?

#1ce2ac on white scores 1.68:1, which fails WCAG AA at every size. Darken it to #108363 to reach 4.5:1, or #0C634B for 7:1.

What is the complementary color of #1ce2ac?

#E21C52 sits directly opposite on the wheel. Softer options are the split-complements #E21CB5 and #E2491C, which give the same contrast with far less vibration.

What colors go well with #1ce2ac?

For interface work: #F4FAF9 as the surface, #C0EDE0 for borders, #4B9B85 for secondary text, #E71784 as an accent and #0E7156 for hover and pressed states. For a palette, the analogous pair #1CE249 and #1CB5E2 stays calm, while #E21C52 is the loudest partner.

What is #1ce2ac in CMYK for printing?

cmyk(88%, 0%, 24%, 11%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #1ce2ac warm or cool?

Cool — it scores 81 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #1CE263; nudged cooler, #19D2E5.

Which Tailwind color is closest to #1ce2ac?

The emerald family — its 500 step is #10b981, ΔE2000 10.5 away. That is a visible difference, so define #1ce2ac as a custom token rather than reaching for the built-in.

How do I use #1ce2ac in Tailwind CSS?

Inline it as an arbitrary value with bg-[#1ce2ac] or text-[#1ce2ac], 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 #1ce2ac with 50% opacity?

rgba(28, 226, 172, 0.5), or #1ce2ac80 in eight-digit hex. Over white that composites to #8EF1D6; over black, #0E7156.

Is #1ce2ac a web-safe color?

No. The nearest web-safe colour is #33CC99, ΔE2000 5.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #1ce2ac 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 #1ce2ac?
