How to use #2f805f

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Body text and links on white
  • 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
  • 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

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.

#2f805f, answered

What color is #2f805f?

#2f805f is a dark vivid green, closest to Sea Green (ΔE2000 6). It sits at 156° on the hue wheel with 46% saturation and 34% lightness, which reads as cool.

What is the RGB value of #2f805f?

rgb(47, 128, 95) — 47 red, 128 green and 95 blue out of 255, or 18.4% / 50.2% / 37.3% by channel.

What is #2f805f in HSL and HSV?

hsl(156, 46%, 34%) and hsv(156, 63%, 50%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #2f805f a light or a dark color?

It is a dark color. Relative luminance is 0.1687 and perceived brightness is 42%, so white text on it reaches 4.80:1.

Should I use black or white text on #2f805f?

White. It scores 4.80:1 against #2f805f, versus 4.37:1 for black — AA at any size.

Is #2f805f accessible on a white background?

#2f805f on white scores 4.80:1, which clears AA at every size but not AAA.

What is the complementary color of #2f805f?

#802F50 sits directly opposite on the wheel. Softer options are the split-complements #802F78 and #80372F, which give the same contrast with far less vibration.

What colors go well with #2f805f?

For interface work: #F4FAF8 as the surface, #C3E9DA for borders, #4B9B7A for secondary text, #832B65 as an accent and #225D45 for hover and pressed states. For a palette, the analogous pair #2F8037 and #2F7880 stays calm, while #802F50 is the loudest partner.

What is #2f805f in CMYK for printing?

cmyk(63%, 0%, 26%, 50%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #2f805f warm or cool?

Cool — it scores 77 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #2F8041; nudged cooler, #2D827E.

Which Tailwind color is closest to #2f805f?

The emerald family — its 500 step is #10b981, ΔE2000 18.4 away. That is a visible difference, so define #2f805f as a custom token rather than reaching for the built-in.

How do I use #2f805f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#2f805f] or text-[#2f805f], 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 #2f805f with 50% opacity?

rgba(47, 128, 95, 0.5), or #2f805f80 in eight-digit hex. Over white that composites to #97C0AF; over black, #184030.

Is #2f805f a web-safe color?
