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 #abcc17

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
  • 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 #60730D
Safe as a 1px border on white
No — use #859E12

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 low lightness adds weight and formality.

Worth knowing

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

Transparency

What each alpha value actually composites to. The top row is #abcc17 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.

#abcc17, answered

What color is #abcc17?

#abcc17 is a dark electric green, closest to Yellow Green (ΔE2000 4.2). It sits at 71° on the hue wheel with 80% saturation and 45% lightness, which reads as warm.

What is the RGB value of #abcc17?

rgb(171, 204, 23) — 171 red, 204 green and 23 blue out of 255, or 67.1% / 80% / 9% by channel.

What is #abcc17 in HSL and HSV?

hsl(71, 80%, 45%) and hsv(71, 89%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #abcc17 a light or a dark color?

It is a light color. Relative luminance is 0.5191 and perceived brightness is 71%, so black text on it reaches 11.38:1.

Should I use black or white text on #abcc17?

Black. It scores 11.38:1 against #abcc17, versus 1.85:1 for white — AAA at any size.

Is #abcc17 accessible on a white background?

#abcc17 on white scores 1.85:1, which fails WCAG AA at every size. Darken it to #6A7E0E to reach 4.5:1, or #4F5E0B for 7:1.

What is the complementary color of #abcc17?

#3817CC sits directly opposite on the wheel. Softer options are the split-complements #1751CC and #9217CC, which give the same contrast with far less vibration.

What colors go well with #abcc17?

For interface work: #F9FAF4 as the surface, #E4EDC0 for borders, #8C9B4B for secondary text, #121FD0 as an accent and #60730D for hover and pressed states. For a palette, the analogous pair #CC9217 and #51CC17 stays calm, while #3817CC is the loudest partner.

What is #abcc17 in CMYK for printing?

cmyk(16%, 0%, 89%, 20%). 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 #abcc17 warm or cool?

Warm — it scores 34 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CCAA17; nudged cooler, #69CE15.

Which Tailwind color is closest to #abcc17?

The lime family — its 500 step is #84cc16, ΔE2000 6.6 away. That is a visible difference, so define #abcc17 as a custom token rather than reaching for the built-in.

How do I use #abcc17 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#abcc17] or text-[#abcc17], 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 #abcc17 with 50% opacity?

rgba(171, 204, 23, 0.5), or #abcc1780 in eight-digit hex. Over white that composites to #D5E68B; over black, #56660C.

Is #abcc17 a web-safe color?

No. The nearest web-safe colour is #99CC00, ΔE2000 3.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #abcc17 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 #abcc17?
