Color scale — 50 to 950

How to use #9eb41c

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
  • Headers, footers and dark-mode surfaces
  • 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
  • Black text placed on it
  • 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 #616E11
Safe as a 1px border on white
No — use #8B9E19

Meaning and mood

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

optimisticalertcheap-and-cheerfulvisible

The most visible hue at low light levels, which is why it owns warnings, hazard tape and value retail.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The low lightness adds weight and formality.

Worth knowing

Almost never passes contrast against white. Treat it as a surface or a marker, not as text.

Transparency

What each alpha value actually composites to. The top row is #9eb41c 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.

#9eb41c, answered

What color is #9eb41c?

#9eb41c is a dark vivid yellow, closest to Yellow Green (ΔE2000 7.6). It sits at 69° on the hue wheel with 73% saturation and 41% lightness, which reads as warm.

What is the RGB value of #9eb41c?

rgb(158, 180, 28) — 158 red, 180 green and 28 blue out of 255, or 62% / 70.6% / 11% by channel.

What is #9eb41c in HSL and HSV?

hsl(69, 73%, 41%) and hsv(69, 84%, 71%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #9eb41c a light or a dark color?

It is a mid-tone. Relative luminance is 0.4000 and perceived brightness is 64%, so black text on it reaches 9.00:1.

Should I use black or white text on #9eb41c?

Black. It scores 9.00:1 against #9eb41c, versus 2.33:1 for white — AAA at any size.

Is #9eb41c accessible on a white background?

#9eb41c on white scores 2.33:1, which fails WCAG AA at every size. Darken it to #6C7B13 to reach 4.5:1, or #515C0E for 7:1.

What is the complementary color of #9eb41c?

#321CB4 sits directly opposite on the wheel. Softer options are the split-complements #1C52B4 and #7E1CB4, which give the same contrast with far less vibration.

What colors go well with #9eb41c?

For interface work: #FAFAF4 as the surface, #E6EDC0 for borders, #8F9B4B for secondary text, #1829B8 as an accent and #616E11 for hover and pressed states. For a palette, the analogous pair #B47E1C and #52B41C stays calm, while #321CB4 is the loudest partner.

What is #9eb41c in CMYK for printing?

cmyk(12%, 0%, 84%, 29%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #9eb41c warm or cool?

Warm — it scores 32 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B4921C; nudged cooler, #66B61A.

Which Tailwind color is closest to #9eb41c?

The lime family — its 500 step is #84cc16, ΔE2000 9.1 away. That is a visible difference, so define #9eb41c as a custom token rather than reaching for the built-in.

How do I use #9eb41c in Tailwind CSS?

Inline it as an arbitrary value with bg-[#9eb41c] or text-[#9eb41c], 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 #9eb41c with 50% opacity?

rgba(158, 180, 28, 0.5), or #9eb41c80 in eight-digit hex. Over white that composites to #CFDA8E; over black, #4F5A0E.

Is #9eb41c a web-safe color?

No. The nearest web-safe colour is #99CC33, ΔE2000 7.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #9eb41c mean?
