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 #b3cfb5

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 #314E33
Safe as a 1px border on white
No — use #68A06C

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.

#b3cfb5, answered

What color is #b3cfb5?

#b3cfb5 is a light soft green, closest to Dark Sea Green (ΔE2000 8.8). It sits at 124° on the hue wheel with 23% saturation and 76% lightness, which reads as cool.

What is the RGB value of #b3cfb5?

rgb(179, 207, 181) — 179 red, 207 green and 181 blue out of 255, or 70.2% / 81.2% / 71% by channel.

What is #b3cfb5 in HSL and HSV?

hsl(124, 23%, 76%) and hsv(124, 14%, 81%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b3cfb5 a light or a dark color?

It is a light color. Relative luminance is 0.5755 and perceived brightness is 77%, so black text on it reaches 12.51:1.

Should I use black or white text on #b3cfb5?

Black. It scores 12.51:1 against #b3cfb5, versus 1.68:1 for white — AAA at any size.

Is #b3cfb5 accessible on a white background?

#b3cfb5 on white scores 1.68:1, which fails WCAG AA at every size. Darken it to #507F54 to reach 4.5:1, or #3D603F for 7:1.

What is the complementary color of #b3cfb5?

#CFB3CD sits directly opposite on the wheel. Softer options are the split-complements #C3B3CF and #CFB3BF, which give the same contrast with far less vibration.

What colors go well with #b3cfb5?

For interface work: #F6F9F6 as the surface, #CDDFCE for borders, #598D5D for secondary text, #774B81 as an accent and #314E33 for hover and pressed states. For a palette, the analogous pair #BFCFB3 and #B3CFC3 stays calm, while #CFB3CD is the loudest partner.

What is #b3cfb5 in CMYK for printing?

cmyk(14%, 0%, 13%, 19%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b3cfb5 warm or cool?

Cool — it scores 59 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #BBCFB3; nudged cooler, #B2D0BF.

Which Tailwind color is closest to #b3cfb5?

The teal family — its 500 step is #14b8a6, ΔE2000 18.3 away. That is a visible difference, so define #b3cfb5 as a custom token rather than reaching for the built-in.

How do I use #b3cfb5 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b3cfb5] or text-[#b3cfb5], 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 #b3cfb5 with 50% opacity?

rgba(179, 207, 181, 0.5), or #b3cfb580 in eight-digit hex. Over white that composites to #D9E7DA; over black, #5A685B.

Is #b3cfb5 a web-safe color?

No. The nearest web-safe colour is #CCCCCC, ΔE2000 15.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #b3cfb5 mean?
