How to use #127a35

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.

Transparency

What each alpha value actually composites to. The top row is #127a35 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.

#127a35, answered

What color is #127a35?

#127a35 is a dark vivid green, closest to Green (ΔE2000 6.9). It sits at 140° on the hue wheel with 74% saturation and 28% lightness, which reads as cool.

What is the RGB value of #127a35?

rgb(18, 122, 53) — 18 red, 122 green and 53 blue out of 255, or 7.1% / 47.8% / 20.8% by channel.

What is #127a35 in HSL and HSV?

hsl(140, 74%, 28%) and hsv(140, 85%, 48%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #127a35 a light or a dark color?

It is a dark color. Relative luminance is 0.1430 and perceived brightness is 38%, so white text on it reaches 5.44:1.

Should I use black or white text on #127a35?

White. It scores 5.44:1 against #127a35, versus 3.86:1 for black — AA at any size.

Is #127a35 accessible on a white background?

#127a35 on white scores 5.44:1, which clears AA at every size but not AAA.

What is the complementary color of #127a35?

#7A1257 sits directly opposite on the wheel. Softer options are the split-complements #69127A and #7A1223, which give the same contrast with far less vibration.

What colors go well with #127a35?

For interface work: #F4FAF6 as the surface, #C0EDCF for borders, #4B9B66 for secondary text, #7D0F74 as an accent and #106F30 for hover and pressed states. For a palette, the analogous pair #237A12 and #127A69 stays calm, while #7A1257 is the loudest partner.

What is #127a35 in CMYK for printing?

cmyk(85%, 0%, 57%, 52%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #127a35 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 #157A12; nudged cooler, #117C5C.

Which Tailwind color is closest to #127a35?

The emerald family — its 500 step is #10b981, ΔE2000 21.9 away. That is a visible difference, so define #127a35 as a custom token rather than reaching for the built-in.

How do I use #127a35 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#127a35] or text-[#127a35], 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 #127a35 with 50% opacity?

rgba(18, 122, 53, 0.5), or #127a3580 in eight-digit hex. Over white that composites to #89BD9A; over black, #093D1B.

Is #127a35 a web-safe color?

No. The nearest web-safe colour is #006633, ΔE2000 7.3 away. The palette only matters for legacy displays and some email clients now.
