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 #89df33

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
  • 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 #406E11
Safe as a 1px border on white
No — use #60A61A

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.

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

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

What each alpha value actually composites to. The top row is #89df33 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.

#89df33, answered

What color is #89df33?

#89df33 is a balanced vivid green, closest to Yellow Green (ΔE2000 5.5). It sits at 90° on the hue wheel with 73% saturation and 54% lightness, which reads as neutral.

What is the RGB value of #89df33?

rgb(137, 223, 51) — 137 red, 223 green and 51 blue out of 255, or 53.7% / 87.5% / 20% by channel.

What is #89df33 in HSL and HSV?

hsl(90, 73%, 54%) and hsv(90, 77%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #89df33 a light or a dark color?

It is a light color. Relative luminance is 0.5833 and perceived brightness is 73%, so black text on it reaches 12.67:1.

Should I use black or white text on #89df33?

Black. It scores 12.67:1 against #89df33, versus 1.66:1 for white — AAA at any size.

Is #89df33 accessible on a white background?

#89df33 on white scores 1.66:1, which fails WCAG AA at every size. Darken it to #4C8315 to reach 4.5:1, or #37600F for 7:1.

What is the complementary color of #89df33?

#8933DF sits directly opposite on the wheel. Softer options are the split-complements #3333DF and #DF33DF, which give the same contrast with far less vibration.

What colors go well with #89df33?

For interface work: #F7FAF4 as the surface, #D6EDC0 for borders, #739B4B for secondary text, #5C2EE4 as an accent and #406E11 for hover and pressed states. For a palette, the analogous pair #DFDF33 and #33DF33 stays calm, while #8933DF is the loudest partner.

What is #89df33 in CMYK for printing?

cmyk(39%, 0%, 77%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #89df33 warm or cool?

Neutral — it scores 50 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #C8DF33; nudged cooler, #48E131.

Which Tailwind color is closest to #89df33?

The lime family — its 500 step is #84cc16, ΔE2000 4.7 away. That is a visible difference, so define #89df33 as a custom token rather than reaching for the built-in.

How do I use #89df33 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#89df33] or text-[#89df33], 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 #89df33 with 50% opacity?

rgba(137, 223, 51, 0.5), or #89df3380 in eight-digit hex. Over white that composites to #C4EF99; over black, #45701A.

Is #89df33 a web-safe color?

No. The nearest web-safe colour is #99CC33, ΔE2000 5.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #89df33 mean?
