How to use #7fa921

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
  • Headers, footers and dark-mode surfaces
  • 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
  • Black 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 #506B15
Safe as a 1px border on white
No — use #79A01F

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 low lightness adds weight and formality.

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 #7fa921 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.

#7fa921, answered

What color is #7fa921?

#7fa921 is a dark vivid green, closest to Olive Drab (ΔE2000 8.9). It sits at 79° on the hue wheel with 67% saturation and 40% lightness, which reads as warm.

What is the RGB value of #7fa921?

rgb(127, 169, 33) — 127 red, 169 green and 33 blue out of 255, or 49.8% / 66.3% / 12.9% by channel.

What is #7fa921 in HSL and HSV?

hsl(79, 67%, 40%) and hsv(79, 80%, 66%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #7fa921 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3300 and perceived brightness is 58%, so black text on it reaches 7.60:1.

Should I use black or white text on #7fa921?

Black. It scores 7.60:1 against #7fa921, versus 2.76:1 for white — AAA at any size.

Is #7fa921 accessible on a white background?

#7fa921 on white scores 2.76:1, which fails WCAG AA at every size. Darken it to #5F7E19 to reach 4.5:1, or #486013 for 7:1.

What is the complementary color of #7fa921?

#4B21A9 sits directly opposite on the wheel. Softer options are the split-complements #213BA9 and #8F21A9, which give the same contrast with far less vibration.

What colors go well with #7fa921?

For interface work: #F9FAF4 as the surface, #DFEDC0 for borders, #829B4B for secondary text, #251DAD as an accent and #506B15 for hover and pressed states. For a palette, the analogous pair #A98F21 and #3BA921 stays calm, while #4B21A9 is the loudest partner.

What is #7fa921 in CMYK for printing?

cmyk(25%, 0%, 81%, 34%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #7fa921 warm or cool?

Warm — it scores 40 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #A9A121; nudged cooler, #4CAB1F.

Which Tailwind color is closest to #7fa921?

The lime family — its 500 step is #84cc16, ΔE2000 9.6 away. That is a visible difference, so define #7fa921 as a custom token rather than reaching for the built-in.

How do I use #7fa921 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#7fa921] or text-[#7fa921], 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 #7fa921 with 50% opacity?

rgba(127, 169, 33, 0.5), or #7fa92180 in eight-digit hex. Over white that composites to #BFD490; over black, #405511.

Is #7fa921 a web-safe color?

No. The nearest web-safe colour is #669933, ΔE2000 7.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #7fa921 mean?
