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 #b3ecba

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
  • Card and section backgrounds
  • 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
  • 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 #1A6623
Safe as a 1px border on white
No — use #2AA93A

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 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 #b3ecba 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.

#b3ecba, answered

What color is #b3ecba?

#b3ecba is a light vivid green, closest to Light Green (ΔE2000 8.7). It sits at 127° on the hue wheel with 60% saturation and 81% lightness, which reads as cool.

What is the RGB value of #b3ecba?

rgb(179, 236, 186) — 179 red, 236 green and 186 blue out of 255, or 70.2% / 92.5% / 72.9% by channel.

What is #b3ecba in HSL and HSV?

hsl(127, 60%, 81%) and hsv(127, 24%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b3ecba a light or a dark color?

It is a light color. Relative luminance is 0.7312 and perceived brightness is 84%, so black text on it reaches 15.62:1.

Should I use black or white text on #b3ecba?

Black. It scores 15.62:1 against #b3ecba, versus 1.34:1 for white — AAA at any size.

Is #b3ecba accessible on a white background?

#b3ecba on white scores 1.34:1, which fails WCAG AA at every size. Darken it to #22882F to reach 4.5:1, or #196422 for 7:1.

What is the complementary color of #b3ecba?

#ECB3E5 sits directly opposite on the wheel. Softer options are the split-complements #D7B3EC and #ECB3C9, which give the same contrast with far less vibration.

What colors go well with #b3ecba?

For interface work: #F4FAF5 as the surface, #C0EDC5 for borders, #4B9B54 for secondary text, #9625A7 as an accent and #1A6623 for hover and pressed states. For a palette, the analogous pair #C9ECB3 and #B3ECD7 stays calm, while #ECB3E5 is the loudest partner.

What is #b3ecba in CMYK for printing?

cmyk(24%, 0%, 21%, 8%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b3ecba 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 #C1ECB3; nudged cooler, #B2EDCF.

Which Tailwind color is closest to #b3ecba?

The green family — its 500 step is #22c55e, ΔE2000 17.4 away. That is a visible difference, so define #b3ecba as a custom token rather than reaching for the built-in.

How do I use #b3ecba in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b3ecba] or text-[#b3ecba], 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 #b3ecba with 50% opacity?

rgba(179, 236, 186, 0.5), or #b3ecba80 in eight-digit hex. Over white that composites to #D9F6DD; over black, #5A765D.

Is #b3ecba a web-safe color?

No. The nearest web-safe colour is #CCFFCC, ΔE2000 4.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #b3ecba 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 #b3ecba?
