How to use #809178

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
  • Borders, dividers and quiet backgrounds
  • Long-form reading surfaces
  • Brand accents, badges and data highlights
Use with care
  • Small text on white — under 4.5:1
  • 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 #3D4639
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.

With almost no chroma left, the family association is barely present; treat it as a neutral that happens to lean this way. The mid lightness keeps it versatile in both themes.

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 #809178 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.

#809178, answered

What color is #809178?

#809178 is a balanced muted green, closest to Dark Sea Green (ΔE2000 13.9). It sits at 101° on the hue wheel with 10% saturation and 52% lightness, which reads as neutral.

What is the RGB value of #809178?

rgb(128, 145, 120) — 128 red, 145 green and 120 blue out of 255, or 50.2% / 56.9% / 47.1% by channel.

What is #809178 in HSL and HSV?

hsl(101, 10%, 52%) and hsv(101, 17%, 57%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #809178 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2620 and perceived brightness is 54%, so black text on it reaches 6.24:1.

Should I use black or white text on #809178?

Black. It scores 6.24:1 against #809178, versus 3.37:1 for white — AA at any size.

Is #809178 accessible on a white background?

#809178 on white scores 3.37:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #6A7962 to reach 4.5:1, or #4F5A49 for 7:1.

What is the complementary color of #809178?

#897891 sits directly opposite on the wheel. Softer options are the split-complements #7D7891 and #91788D, which give the same contrast with far less vibration.

What colors go well with #809178?

For interface work: #F7F8F7 as the surface, #D5DAD2 for borders, #6F7E67 for secondary text, #827396 as an accent and #3D4639 for hover and pressed states. For a palette, the analogous pair #8D9178 and #78917D stays calm, while #897891 is the loudest partner.

What is #809178 in CMYK for printing?

cmyk(12%, 0%, 17%, 43%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #809178 warm or cool?

Neutral — it scores 51 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #899178; nudged cooler, #769477.

Which Tailwind color is closest to #809178?

The neutral family — its 500 step is #737373, ΔE2000 16.7 away. That is a visible difference, so define #809178 as a custom token rather than reaching for the built-in.

How do I use #809178 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#809178] or text-[#809178], 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.
