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.

Color scale — 50 to 950

How to use #9eb03f

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 #545E22
Safe as a 1px border on white
No — use #8A9A37

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 mid lightness keeps it versatile in both themes.

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 #9eb03f 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.

#9eb03f, answered

What color is #9eb03f?

#9eb03f is a balanced vivid yellow, closest to Dark Khaki (ΔE2000 8.3). It sits at 70° on the hue wheel with 47% saturation and 47% lightness, which reads as warm.

What is the RGB value of #9eb03f?

rgb(158, 176, 63) — 158 red, 176 green and 63 blue out of 255, or 62% / 69% / 24.7% by channel.

What is #9eb03f in HSL and HSV?

hsl(70, 47%, 47%) and hsv(70, 64%, 69%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #9eb03f a light or a dark color?

It is a mid-tone. Relative luminance is 0.3868 and perceived brightness is 63%, so black text on it reaches 8.74:1.

Should I use black or white text on #9eb03f?

Black. It scores 8.74:1 against #9eb03f, versus 2.40:1 for white — AAA at any size.

Is #9eb03f accessible on a white background?

#9eb03f on white scores 2.40:1, which fails WCAG AA at every size. Darken it to #6F7C2C to reach 4.5:1, or #545E21 for 7:1.

What is the complementary color of #9eb03f?

#513FB0 sits directly opposite on the wheel. Softer options are the split-complements #3F65B0 and #8A3FB0, which give the same contrast with far less vibration.

What colors go well with #9eb03f?

For interface work: #F9FAF4 as the surface, #E3E9C3 for borders, #8E9B4B for secondary text, #3A45B5 as an accent and #545E22 for hover and pressed states. For a palette, the analogous pair #B08A3F and #65B03F stays calm, while #513FB0 is the loudest partner.

What is #9eb03f in CMYK for printing?

cmyk(10%, 0%, 64%, 31%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #9eb03f warm or cool?

Warm — it scores 33 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B0993F; nudged cooler, #74B33D.

Which Tailwind color is closest to #9eb03f?

The lime family — its 500 step is #84cc16, ΔE2000 10.3 away. That is a visible difference, so define #9eb03f as a custom token rather than reaching for the built-in.

How do I use #9eb03f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#9eb03f] or text-[#9eb03f], 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 #9eb03f with 50% opacity?

rgba(158, 176, 63, 0.5), or #9eb03f80 in eight-digit hex. Over white that composites to #CFD89F; over black, #4F5820.

Is #9eb03f a web-safe color?

No. The nearest web-safe colour is #999933, ΔE2000 7.5 away. The palette only matters for legacy displays and some email clients now.
