How to use #819087

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
  • Neutral UI chrome and typography
Use with care
  • Small text on white — under 4.5:1
  • 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 #3C443F
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.

neutralquieteditorialengineered

Grey is the material the rest of the interface is built from: type, rules, surfaces, disabled states.

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

Mid-greys are where accessibility quietly fails — check every step of your ladder, not just the ends.

Transparency

What each alpha value actually composites to. The top row is #819087 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.

#819087, answered

What color is #819087?

#819087 is a balanced muted gray, closest to Gray (ΔE2000 10). It sits at 144° on the hue wheel with 6% saturation and 54% lightness, which reads as neutral.

What is the RGB value of #819087?

rgb(129, 144, 135) — 129 red, 144 green and 135 blue out of 255, or 50.6% / 56.5% / 52.9% by channel.

What is #819087 in HSL and HSV?

hsl(144, 6%, 54%) and hsv(144, 10%, 56%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #819087 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2636 and perceived brightness is 54%, so black text on it reaches 6.27:1.

Should I use black or white text on #819087?

Black. It scores 6.27:1 against #819087, versus 3.35:1 for white — AA at any size.

Is #819087 accessible on a white background?

#819087 on white scores 3.35:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #6A7970 to reach 4.5:1, or #505B54 for 7:1.

What is the complementary color of #819087?

#90818A sits directly opposite on the wheel. Softer options are the split-complements #8E8190 and #908182, which give the same contrast with far less vibration.

What colors go well with #819087?

For interface work: #F7F8F7 as the surface, #D4D9D6 for borders, #6C7A71 for secondary text, #957C91 as an accent and #3C443F for hover and pressed states. For a palette, the analogous pair #829081 and #81908E stays calm, while #90818A is the loudest partner.

What is #819087 in CMYK for printing?

cmyk(10%, 0%, 6%, 44%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #819087 warm or cool?

Neutral — it scores 54 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #9D8B7E; nudged cooler, #728395.

Which Tailwind color is closest to #819087?

The neutral family — its 500 step is #737373, ΔE2000 13.2 away. That is a visible difference, so define #819087 as a custom token rather than reaching for the built-in.

How do I use #819087 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#819087] or text-[#819087], 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 #819087 with 50% opacity?
