How to use #047c2f

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. 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.

#047c2f, answered

What color is #047c2f?

#047c2f is a dark electric green, closest to Green (ΔE2000 5.6). It sits at 142° on the hue wheel with 94% saturation and 25% lightness, which reads as cool.

What is the RGB value of #047c2f?

rgb(4, 124, 47) — 4 red, 124 green and 47 blue out of 255, or 1.6% / 48.6% / 18.4% by channel.

What is #047c2f in HSL and HSV?

hsl(142, 94%, 25%) and hsv(142, 97%, 49%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #047c2f a light or a dark color?

It is a dark color. Relative luminance is 0.1465 and perceived brightness is 38%, so white text on it reaches 5.34:1.

Should I use black or white text on #047c2f?

White. It scores 5.34:1 against #047c2f, versus 3.93:1 for black — AA at any size.

Is #047c2f accessible on a white background?

#047c2f on white scores 5.34:1, which clears AA at every size but not AAA.

What is the complementary color of #047c2f?

#7C0451 sits directly opposite on the wheel. Softer options are the split-complements #6B047C and #7C0415, which give the same contrast with far less vibration.

What colors go well with #047c2f?

For interface work: #F4FAF6 as the surface, #C0EDD0 for borders, #4B9B67 for secondary text, #7F0171 as an accent and #047C2F for hover and pressed states. For a palette, the analogous pair #157C04 and #047C6B stays calm, while #7C0451 is the loudest partner.

What is #047c2f in CMYK for printing?

cmyk(97%, 0%, 62%, 51%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #047c2f warm or cool?

Cool — it scores 71 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #057C04; nudged cooler, #037D5C.

Which Tailwind color is closest to #047c2f?

The emerald family — its 500 step is #10b981, ΔE2000 21.7 away. That is a visible difference, so define #047c2f as a custom token rather than reaching for the built-in.

How do I use #047c2f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#047c2f] or text-[#047c2f], 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 #047c2f with 50% opacity?

rgba(4, 124, 47, 0.5), or #047c2f80 in eight-digit hex. Over white that composites to #82BE97; over black, #023E18.

Is #047c2f a web-safe color?

No. The nearest web-safe colour is #006633, ΔE2000 8.4 away. The palette only matters for legacy displays and some email clients now.
