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 #aaddbd

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 #245B39
Safe as a 1px border on white
No — use #43A768

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 #aaddbd 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.

#aaddbd, answered

What color is #aaddbd?

#aaddbd is a light soft green, closest to Medium Aqua Marine (ΔE2000 9.2). It sits at 142° on the hue wheel with 43% saturation and 77% lightness, which reads as cool.

What is the RGB value of #aaddbd?

rgb(170, 221, 189) — 170 red, 221 green and 189 blue out of 255, or 66.7% / 86.7% / 74.1% by channel.

What is #aaddbd in HSL and HSV?

hsl(142, 43%, 77%) and hsv(142, 23%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #aaddbd a light or a dark color?

It is a light color. Relative luminance is 0.6393 and perceived brightness is 80%, so black text on it reaches 13.79:1.

Should I use black or white text on #aaddbd?

Black. It scores 13.79:1 against #aaddbd, versus 1.52:1 for white — AAA at any size.

Is #aaddbd accessible on a white background?

#aaddbd on white scores 1.52:1, which fails WCAG AA at every size. Darken it to #348251 to reach 4.5:1, or #27613D for 7:1.

What is the complementary color of #aaddbd?

#DDAACA sits directly opposite on the wheel. Softer options are the split-complements #D7AADD and #DDAAB1, which give the same contrast with far less vibration.

What colors go well with #aaddbd?

For interface work: #F4FAF7 as the surface, #C5E8D2 for borders, #4B9B69 for secondary text, #95378B as an accent and #245B39 for hover and pressed states. For a palette, the analogous pair #B1DDAA and #AADDD7 stays calm, while #DDAACA is the loudest partner.

What is #aaddbd in CMYK for printing?

cmyk(23%, 0%, 15%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #aaddbd warm or cool?

Cool — it scores 72 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AADDAA; nudged cooler, #A9DED0.

Which Tailwind color is closest to #aaddbd?

The emerald family — its 500 step is #10b981, ΔE2000 16.6 away. That is a visible difference, so define #aaddbd as a custom token rather than reaching for the built-in.

How do I use #aaddbd in Tailwind CSS?

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

rgba(170, 221, 189, 0.5), or #aaddbd80 in eight-digit hex. Over white that composites to #D5EEDE; over black, #556F5F.

Is #aaddbd a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 12.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #aaddbd 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 #aaddbd?

The safest is same-hue elevation: linear-gradient(135deg, #D6EFDF, #aaddbd 45%, #245B39). For more colour, a short hue run to #94CCD4 keeps it rich without turning muddy.
