How to use #91bc9d

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 #304F39
Safe as a 1px border on white
No — use #65A175

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.

What each alpha value actually composites to. The top row is #91bc9d 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.

#91bc9d, answered

What color is #91bc9d?

#91bc9d is a light soft green, closest to Dark Sea Green (ΔE2000 3.9). It sits at 137° on the hue wheel with 24% saturation and 65% lightness, which reads as cool.

What is the RGB value of #91bc9d?

rgb(145, 188, 157) — 145 red, 188 green and 157 blue out of 255, or 56.9% / 73.7% / 61.6% by channel.

What is #91bc9d in HSL and HSV?

hsl(137, 24%, 65%) and hsv(137, 23%, 74%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #91bc9d a light or a dark color?

It is a mid-tone. Relative luminance is 0.4442 and perceived brightness is 68%, so black text on it reaches 9.88:1.

Should I use black or white text on #91bc9d?

Black. It scores 9.88:1 against #91bc9d, versus 2.12:1 for white — AAA at any size.

Is #91bc9d accessible on a white background?

#91bc9d on white scores 2.12:1, which fails WCAG AA at every size. Darken it to #4E805C to reach 4.5:1, or #3A6045 for 7:1.

What is the complementary color of #91bc9d?

#BC91B0 sits directly opposite on the wheel. Softer options are the split-complements #B291BC and #BC919B, which give the same contrast with far less vibration.

What colors go well with #91bc9d?

For interface work: #F5F9F7 as the surface, #CCE0D2 for borders, #578F66 for secondary text, #834981 as an accent and #304F39 for hover and pressed states. For a palette, the analogous pair #9BBC91 and #91BCB2 stays calm, while #BC91B0 is the loudest partner.

What is #91bc9d in CMYK for printing?

cmyk(23%, 0%, 17%, 26%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #91bc9d warm or cool?

Cool — it scores 64 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #95BC91; nudged cooler, #8FBEAD.

Which Tailwind color is closest to #91bc9d?

The emerald family — its 500 step is #10b981, ΔE2000 12.8 away. That is a visible difference, so define #91bc9d as a custom token rather than reaching for the built-in.

How do I use #91bc9d in Tailwind CSS?

Inline it as an arbitrary value with bg-[#91bc9d] or text-[#91bc9d], 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 #91bc9d with 50% opacity?

rgba(145, 188, 157, 0.5), or #91bc9d80 in eight-digit hex. Over white that composites to #C8DECE; over black, #495E4F.

Is #91bc9d a web-safe color?

No. The nearest web-safe colour is #99CC99, ΔE2000 6.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #91bc9d mean?
