How to use #299549

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

Works well for
  • Headings from 24px up on white
  • 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
  • Small text on white — under 4.5:1
  • 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
24px / 18.66px bold
Safe as a fill behind white type
No — use #1C6431
Safe as a 1px border on white
Yes

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 #299549 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.

#299549, answered

What color is #299549?

#299549 is a dark vivid green, closest to Sea Green (ΔE2000 5.6). It sits at 138° on the hue wheel with 57% saturation and 37% lightness, which reads as cool.

What is the RGB value of #299549?

rgb(41, 149, 73) — 41 red, 149 green and 73 blue out of 255, or 16.1% / 58.4% / 28.6% by channel.

What is #299549 in HSL and HSV?

hsl(138, 57%, 37%) and hsv(138, 72%, 58%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #299549 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2245 and perceived brightness is 47%, so black text on it reaches 5.49:1.

Should I use black or white text on #299549?

Black. It scores 5.49:1 against #299549, versus 3.83:1 for white — AA at any size.

Is #299549 accessible on a white background?

#299549 on white scores 3.83:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #258541 to reach 4.5:1, or #1C6532 for 7:1.

What is the complementary color of #299549?

#952975 sits directly opposite on the wheel. Softer options are the split-complements #7F2995 and #95293F, which give the same contrast with far less vibration.

What colors go well with #299549?

For interface work: #F4FAF6 as the surface, #C0EDCD for borders, #4B9B62 for secondary text, #992594 as an accent and #1C6431 for hover and pressed states. For a palette, the analogous pair #3F9529 and #29957F stays calm, while #952975 is the loudest partner.

What is #299549 in CMYK for printing?

cmyk(73%, 0%, 51%, 42%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #299549 warm or cool?

Cool — it scores 70 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #319529; nudged cooler, #279771.

Which Tailwind color is closest to #299549?

The emerald family — its 500 step is #10b981, ΔE2000 12.7 away. That is a visible difference, so define #299549 as a custom token rather than reaching for the built-in.

How do I use #299549 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#299549] or text-[#299549], 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 #299549 with 50% opacity?
