Use with care
  • Text on black or near-black surfaces
  • 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

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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. 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.

#2d4a39, answered

What color is #2d4a39?

#2d4a39 is a deep soft green, closest to Dark Slate Gray (ΔE2000 8.6). It sits at 145° on the hue wheel with 24% saturation and 23% lightness, which reads as cool.

What is the RGB value of #2d4a39?

rgb(45, 74, 57) — 45 red, 74 green and 57 blue out of 255, or 17.6% / 29% / 22.4% by channel.

What is #2d4a39 in HSL and HSV?

hsl(145, 24%, 23%) and hsv(145, 39%, 29%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #2d4a39 a light or a dark color?

It is a dark color. Relative luminance is 0.0575 and perceived brightness is 25%, so white text on it reaches 9.77:1.

Should I use black or white text on #2d4a39?

White. It scores 9.77:1 against #2d4a39, versus 2.15:1 for black — AAA at any size.

Is #2d4a39 accessible on a white background?

#2d4a39 on white scores 9.77:1, which clears AAA at every size.

What is the complementary color of #2d4a39?

#4A2D3E sits directly opposite on the wheel. Softer options are the split-complements #472D4A and #4A2D2F, which give the same contrast with far less vibration.

What colors go well with #2d4a39?

For interface work: #F5F9F7 as the surface, #CCE0D4 for borders, #578F6E for secondary text, #4C2B47 as an accent and #304F3D for hover and pressed states. For a palette, the analogous pair #2F4A2D and #2D4A47 stays calm, while #4A2D3E is the loudest partner.

What is #2d4a39 in CMYK for printing?

cmyk(39%, 0%, 23%, 71%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #2d4a39 warm or cool?

Cool — it scores 66 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #2D4A2E; nudged cooler, #2C4B44.

Which Tailwind color is closest to #2d4a39?

The neutral family — its 500 step is #737373, ΔE2000 23 away. That is a visible difference, so define #2d4a39 as a custom token rather than reaching for the built-in.

How do I use #2d4a39 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#2d4a39] or text-[#2d4a39], 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 #2d4a39 with 50% opacity?

rgba(45, 74, 57, 0.5), or #2d4a3980 in eight-digit hex. Over white that composites to #96A59C; over black, #17251D.

Is #2d4a39 a web-safe color?
