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 #9ffdbf

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
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • White text placed on it
  • Status meaning — pair it with an icon or label, never colour alone
  • 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 #037D2C
Safe as a 1px border on white
No — use #04A93C

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

safegrowingnaturalpermissive

Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. The lightness keeps it airy and approachable.

Worth knowing

Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

#9ffdbf, answered

What color is #9ffdbf?

#9ffdbf is a light electric green, closest to Aqua Marine (ΔE2000 6.6). It sits at 140° on the hue wheel with 96% saturation and 81% lightness, which reads as cool.

What is the RGB value of #9ffdbf?

rgb(159, 253, 191) — 159 red, 253 green and 191 blue out of 255, or 62.4% / 99.2% / 74.9% by channel.

What is #9ffdbf in HSL and HSV?

hsl(140, 96%, 81%) and hsv(140, 37%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #9ffdbf a light or a dark color?

It is a light color. Relative luminance is 0.8138 and perceived brightness is 87%, so black text on it reaches 17.28:1.

Should I use black or white text on #9ffdbf?

Black. It scores 17.28:1 against #9ffdbf, versus 1.22:1 for white — AAA at any size.

Is #9ffdbf accessible on a white background?

#9ffdbf on white scores 1.22:1, which fails WCAG AA at every size. Darken it to #03862F to reach 4.5:1, or #026323 for 7:1.

What is the complementary color of #9ffdbf?

#FD9FDD sits directly opposite on the wheel. Softer options are the split-complements #EE9FFD and #FD9FAE, which give the same contrast with far less vibration.

What colors go well with #9ffdbf?

For interface work: #F4FAF6 as the surface, #C0EDCF for borders, #4B9B66 for secondary text, #CC00B9 as an accent and #037D2C for hover and pressed states. For a palette, the analogous pair #AEFD9F and #9FFDEE stays calm, while #FD9FDD is the loudest partner.

What is #9ffdbf in CMYK for printing?

cmyk(37%, 0%, 25%, 1%). 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 #9ffdbf warm or cool?

Cool — it scores 71 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #A2FD9F; nudged cooler, #9EFEE2.

Which Tailwind color is closest to #9ffdbf?

The green family — its 500 step is #22c55e, ΔE2000 17.1 away. That is a visible difference, so define #9ffdbf as a custom token rather than reaching for the built-in.

How do I use #9ffdbf in Tailwind CSS?

Inline it as an arbitrary value with bg-[#9ffdbf] or text-[#9ffdbf], 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 #9ffdbf with 50% opacity?

rgba(159, 253, 191, 0.5), or #9ffdbf80 in eight-digit hex. Over white that composites to #CFFEDF; over black, #507F60.

Is #9ffdbf a web-safe color?

No. The nearest web-safe colour is #99FFCC, ΔE2000 3 away. The palette only matters for legacy displays and some email clients now.

What does the color #9ffdbf mean?

As a green, it reads safe, growing, natural. Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #9ffdbf?

The safest is same-hue elevation: linear-gradient(135deg, #DBFEE7, #9ffdbf 45%, #037D2C). For more colour, a short hue run to #81F1FC keeps it rich without turning muddy.
