  • Brand accents, badges and data highlights
Use with care
  • Text on black or near-black surfaces
  • Full-page backgrounds — tiring over long sessions
  • Black text placed on it
  • 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.

trustedcalmcompetentcorporate

The default of institutions for a reason: blue is read as stable and safe across nearly every culture that has been surveyed.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. The low lightness adds weight and formality.

Worth knowing

It is also the most crowded hue on the web. Distinctiveness has to come from your other choices.

Transparency

What each alpha value actually composites to. The top row is #080f80 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.

Very dark values collapse into each other on cheap panels — leave more lightness between your darkest steps than the numbers suggest.

#080f80, answered

What color is #080f80?

#080f80 is a dark electric blue, closest to Navy (ΔE2000 2.4). It sits at 237° on the hue wheel with 88% saturation and 27% lightness, which reads as cool.

What is the RGB value of #080f80?

rgb(8, 15, 128) — 8 red, 15 green and 128 blue out of 255, or 3.1% / 5.9% / 50.2% by channel.

What is #080f80 in HSL and HSV?

hsl(237, 88%, 27%) and hsv(237, 94%, 50%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #080f80 a light or a dark color?

It is a dark color. Relative luminance is 0.0195 and perceived brightness is 18%, so white text on it reaches 15.10:1.

Should I use black or white text on #080f80?

White. It scores 15.10:1 against #080f80, versus 1.39:1 for black — AAA at any size.

Is #080f80 accessible on a white background?

#080f80 on white scores 15.10:1, which clears AAA at every size.

What is the complementary color of #080f80?

#807908 sits directly opposite on the wheel. Softer options are the split-complements #803D08 and #4B8008, which give the same contrast with far less vibration.

What colors go well with #080f80?

For interface work: #F4F5FA as the surface, #C0C2ED for borders, #4B4F9B for secondary text, #835C05 as an accent and #080E78 for hover and pressed states. For a palette, the analogous pair #084B80 and #3D0880 stays calm, while #807908 is the loudest partner.

What is #080f80 in CMYK for printing?

cmyk(94%, 88%, 0%, 50%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #080f80 warm or cool?

Cool — it scores 85 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #2D0880; nudged cooler, #072D81.

Which Tailwind color is closest to #080f80?

The indigo family — its 500 step is #6366f1, ΔE2000 28.4 away. That is a visible difference, so define #080f80 as a custom token rather than reaching for the built-in.

How do I use #080f80 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#080f80] or text-[#080f80], 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 #080f80 with 50% opacity?

rgba(8, 15, 128, 0.5), or #080f8080 in eight-digit hex. Over white that composites to #8487C0; over black, #040840.

Is #080f80 a web-safe color?
