How to use #7fd591

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 #1F602D
Safe as a 1px border on white
No — use #37A84F

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 #7fd591 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.

#7fd591, answered

What color is #7fd591?

#7fd591 is a light vivid green, closest to Light Green (ΔE2000 6.9). It sits at 133° on the hue wheel with 51% saturation and 67% lightness, which reads as cool.

What is the RGB value of #7fd591?

rgb(127, 213, 145) — 127 red, 213 green and 145 blue out of 255, or 49.8% / 83.5% / 56.9% by channel.

What is #7fd591 in HSL and HSV?

hsl(133, 51%, 67%) and hsv(133, 40%, 84%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #7fd591 a light or a dark color?

It is a light color. Relative luminance is 0.5414 and perceived brightness is 72%, so black text on it reaches 11.83:1.

Should I use black or white text on #7fd591?

Black. It scores 11.83:1 against #7fd591, versus 1.78:1 for white — AAA at any size.

Is #7fd591 accessible on a white background?

#7fd591 on white scores 1.78:1, which fails WCAG AA at every size. Darken it to #2C853F to reach 4.5:1, or #20632E for 7:1.

What is the complementary color of #7fd591?

#D57FC3 sits directly opposite on the wheel. Softer options are the split-complements #BC7FD5 and #D57F98, which give the same contrast with far less vibration.

What colors go well with #7fd591?

For interface work: #F4FAF6 as the surface, #C2EBCA for borders, #4B9B5B for secondary text, #9A2F9D as an accent and #1F602D for hover and pressed states. For a palette, the analogous pair #98D57F and #7FD5BC stays calm, while #D57FC3 is the loudest partner.

What is #7fd591 in CMYK for printing?

cmyk(40%, 0%, 32%, 17%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #7fd591 warm or cool?

Cool — it scores 68 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #8DD57F; nudged cooler, #7DD7B1.

Which Tailwind color is closest to #7fd591?

The green family — its 500 step is #22c55e, ΔE2000 9.3 away. That is a visible difference, so define #7fd591 as a custom token rather than reaching for the built-in.

How do I use #7fd591 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#7fd591] or text-[#7fd591], 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 #7fd591 with 50% opacity?

rgba(127, 213, 145, 0.5), or #7fd59180 in eight-digit hex. Over white that composites to #BFEAC8; over black, #406B49.

Is #7fd591 a web-safe color?

No. The nearest web-safe colour is #66CC99, ΔE2000 5.3 away. The palette only matters for legacy displays and some email clients now.
