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 #1fdba0

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 #107052
Safe as a 1px border on white
No — use #17A579

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 #1fdba0 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.

#1fdba0, answered

What color is #1fdba0?

#1fdba0 is a balanced electric cyan, closest to Medium Aqua Marine (ΔE2000 6.8). It sits at 161° on the hue wheel with 75% saturation and 49% lightness, which reads as cool.

What is the RGB value of #1fdba0?

rgb(31, 219, 160) — 31 red, 219 green and 160 blue out of 255, or 12.2% / 85.9% / 62.7% by channel.

What is #1fdba0 in HSL and HSV?

hsl(161, 75%, 49%) and hsv(161, 86%, 86%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #1fdba0 a light or a dark color?

It is a light color. Relative luminance is 0.5349 and perceived brightness is 69%, so black text on it reaches 11.70:1.

Should I use black or white text on #1fdba0?

Black. It scores 11.70:1 against #1fdba0, versus 1.80:1 for white — AAA at any size.

Is #1fdba0 accessible on a white background?

#1fdba0 on white scores 1.80:1, which fails WCAG AA at every size. Darken it to #138662 to reach 4.5:1, or #0E6248 for 7:1.

What is the complementary color of #1fdba0?

#DB1F5A sits directly opposite on the wheel. Softer options are the split-complements #DB1FB8 and #DB421F, which give the same contrast with far less vibration.

What colors go well with #1fdba0?

For interface work: #F4FAF8 as the surface, #C0EDDF for borders, #4B9B82 for secondary text, #E01A89 as an accent and #107052 for hover and pressed states. For a palette, the analogous pair #1FDB42 and #1FB8DB stays calm, while #DB1F5A is the loudest partner.

What is #1fdba0 in CMYK for printing?

cmyk(86%, 0%, 27%, 14%). 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 #1fdba0 warm or cool?

Cool — it scores 80 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #1FDB5B; nudged cooler, #1CD3DD.

Which Tailwind color is closest to #1fdba0?

The emerald family — its 500 step is #10b981, ΔE2000 8.7 away. That is a visible difference, so define #1fdba0 as a custom token rather than reaching for the built-in.

How do I use #1fdba0 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#1fdba0] or text-[#1fdba0], 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 #1fdba0 with 50% opacity?

rgba(31, 219, 160, 0.5), or #1fdba080 in eight-digit hex. Over white that composites to #8FEDD0; over black, #106E50.

Is #1fdba0 a web-safe color?

No. The nearest web-safe colour is #33CC99, ΔE2000 3.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #1fdba0 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 #1fdba0?
