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 #aec6af

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 #354B36
Safe as a 1px border on white
No — use #759E77

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.

Transparency

What each alpha value actually composites to. The top row is #aec6af 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.

#aec6af, answered

What color is #aec6af?

#aec6af is a light soft green, closest to Dark Sea Green (ΔE2000 8.7). It sits at 123° on the hue wheel with 17% saturation and 73% lightness, which reads as neutral.

What is the RGB value of #aec6af?

rgb(174, 198, 175) — 174 red, 198 green and 175 blue out of 255, or 68.2% / 77.6% / 68.6% by channel.

What is #aec6af in HSL and HSV?

hsl(123, 17%, 73%) and hsv(123, 12%, 78%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #aec6af a light or a dark color?

It is a light color. Relative luminance is 0.5248 and perceived brightness is 74%, so black text on it reaches 11.50:1.

Should I use black or white text on #aec6af?

Black. It scores 11.50:1 against #aec6af, versus 1.83:1 for white — AAA at any size.

Is #aec6af accessible on a white background?

#aec6af on white scores 1.83:1, which fails WCAG AA at every size. Darken it to #587D5A to reach 4.5:1, or #435F44 for 7:1.

What is the complementary color of #aec6af?

#C6AEC5 sits directly opposite on the wheel. Softer options are the split-complements #BBAEC6 and #C6AEB9, which give the same contrast with far less vibration.

What colors go well with #aec6af?

For interface work: #F6F9F6 as the surface, #CFDDD0 for borders, #5F8760 for secondary text, #73507C as an accent and #354B36 for hover and pressed states. For a palette, the analogous pair #B9C6AE and #AEC6BB stays calm, while #C6AEC5 is the loudest partner.

What is #aec6af in CMYK for printing?

cmyk(12%, 0%, 12%, 22%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #aec6af warm or cool?

Neutral — it scores 57 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B6C6AE; nudged cooler, #ACC7B7.

Which Tailwind color is closest to #aec6af?

The teal family — its 500 step is #14b8a6, ΔE2000 17.9 away. That is a visible difference, so define #aec6af as a custom token rather than reaching for the built-in.

How do I use #aec6af in Tailwind CSS?

Inline it as an arbitrary value with bg-[#aec6af] or text-[#aec6af], 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 #aec6af with 50% opacity?

rgba(174, 198, 175, 0.5), or #aec6af80 in eight-digit hex. Over white that composites to #D7E3D7; over black, #576358.

Is #aec6af a web-safe color?

No. The nearest web-safe colour is #99CC99, ΔE2000 9 away. The palette only matters for legacy displays and some email clients now.

What does the color #aec6af 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 #aec6af?
