  • Brand accents, badges and data highlights
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
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.

urgentappetisingboldphysical

Red arrives before the rest of the page does. It raises attention and appetite, which is why it runs food, sport and clearance pricing.

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

It is also the universal error colour. Use it as a brand accent and users may read a warning that is not there.

What each alpha value actually composites to. The top row is #78313f 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.

#78313f, answered

#78313f is a dark soft red, closest to Brown (ΔE2000 13.5). It sits at 348° on the hue wheel with 42% saturation and 33% lightness, which reads as warm.

What is the RGB value of #78313f?

rgb(120, 49, 63) — 120 red, 49 green and 63 blue out of 255, or 47.1% / 19.2% / 24.7% by channel.

What is #78313f in HSL and HSV?

hsl(348, 42%, 33%) and hsv(348, 59%, 47%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #78313f a light or a dark color?

It is a dark color. Relative luminance is 0.0655 and perceived brightness is 31%, so white text on it reaches 9.09:1.

Should I use black or white text on #78313f?

White. It scores 9.09:1 against #78313f, versus 2.31:1 for black — AAA at any size.

Is #78313f accessible on a white background?

#78313f on white scores 9.09:1, which clears AAA at every size.

What is the complementary color of #78313f?

#31786A sits directly opposite on the wheel. Softer options are the split-complements #317846 and #316278, which give the same contrast with far less vibration.

What colors go well with #78313f?

For interface work: #FAF4F5 as the surface, #E7C5CC for borders, #9B4B5A for secondary text, #2E7B59 as an accent and #5B2530 for hover and pressed states. For a palette, the analogous pair #783162 and #784631 stays calm, while #31786A is the loudest partner.

What is #78313f in CMYK for printing?

cmyk(0%, 59%, 48%, 53%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Warm — it scores 23 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #783D31; nudged cooler, #7A2F59.

Which Tailwind color is closest to #78313f?

The stone family — its 500 step is #78716c, ΔE2000 25.8 away. That is a visible difference, so define #78313f as a custom token rather than reaching for the built-in.

How do I use #78313f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#78313f] or text-[#78313f], 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 #78313f with 50% opacity?

rgba(120, 49, 63, 0.5), or #78313f80 in eight-digit hex. Over white that composites to #BC989F; over black, #3C1920.

Is #78313f a web-safe color?
