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 #acceb9

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • 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 #2F503C
Safe as a 1px border on white
No — use #62A27B

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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. 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.

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.

#acceb9, answered

What color is #acceb9?

#acceb9 is a light soft green, closest to Dark Sea Green (ΔE2000 9.2). It sits at 143° on the hue wheel with 26% saturation and 74% lightness, which reads as cool.

What is the RGB value of #acceb9?

rgb(172, 206, 185) — 172 red, 206 green and 185 blue out of 255, or 67.5% / 80.8% / 72.5% by channel.

What is #acceb9 in HSL and HSV?

hsl(143, 26%, 74%) and hsv(143, 17%, 81%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #acceb9 a light or a dark color?

It is a light color. Relative luminance is 0.5642 and perceived brightness is 76%, so black text on it reaches 12.28:1.

Should I use black or white text on #acceb9?

Black. It scores 12.28:1 against #acceb9, versus 1.71:1 for white — AAA at any size.

Is #acceb9 accessible on a white background?

#acceb9 on white scores 1.71:1, which fails WCAG AA at every size. Darken it to #4C8160 to reach 4.5:1, or #396148 for 7:1.

What is the complementary color of #acceb9?

#CEACC1 sits directly opposite on the wheel. Softer options are the split-complements #CAACCE and #CEACB0, which give the same contrast with far less vibration.

What colors go well with #acceb9?

For interface work: #F5F9F7 as the surface, #CCE1D4 for borders, #55906C for secondary text, #85477C as an accent and #2F503C for hover and pressed states. For a palette, the analogous pair #B0CEAC and #ACCECA stays calm, while #CEACC1 is the loudest partner.

What is #acceb9 in CMYK for printing?

cmyk(17%, 0%, 10%, 19%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #acceb9 warm or cool?

Cool — it scores 66 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #ACCEAC; nudged cooler, #ABCFC6.

Which Tailwind color is closest to #acceb9?

The teal family — its 500 step is #14b8a6, ΔE2000 16.6 away. That is a visible difference, so define #acceb9 as a custom token rather than reaching for the built-in.

How do I use #acceb9 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#acceb9] or text-[#acceb9], 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 #acceb9 with 50% opacity?

rgba(172, 206, 185, 0.5), or #acceb980 in eight-digit hex. Over white that composites to #D6E7DC; over black, #56675D.

Is #acceb9 a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 9.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #acceb9 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 moderate chroma the association is present but not shouted.

What gradient works with #acceb9?

The safest is same-hue elevation: linear-gradient(135deg, #D2E5D9, #acceb9 45%, #2F503C). For more colour, a short hue run to #99BDC3 keeps it rich without turning muddy.
