Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.

  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Full-page backgrounds — tiring over long sessions
  • 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 mid lightness keeps it versatile in both themes.

Worth knowing

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

#085bfe, answered

What color is #085bfe?

#085bfe is a balanced electric blue, closest to Royal Blue (ΔE2000 5.2). It sits at 220° on the hue wheel with 99% saturation and 51% lightness, which reads as cool.

What is the RGB value of #085bfe?

rgb(8, 91, 254) — 8 red, 91 green and 254 blue out of 255, or 3.1% / 35.7% / 99.6% by channel.

What is #085bfe in HSL and HSV?

hsl(220, 99%, 51%) and hsv(220, 97%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #085bfe a light or a dark color?

It is a dark color. Relative luminance is 0.1469 and perceived brightness is 43%, so white text on it reaches 5.33:1.

Should I use black or white text on #085bfe?

White. It scores 5.33:1 against #085bfe, versus 3.94:1 for black — AA at any size.

Is #085bfe accessible on a white background?

#085bfe on white scores 5.33:1, which clears AA at every size but not AAA.

What is the complementary color of #085bfe?

#FEAB08 sits directly opposite on the wheel. Softer options are the split-complements #FE3008 and #D6FE08, which give the same contrast with far less vibration.

What colors go well with #085bfe?

For interface work: #F4F6FA as the surface, #C0CFED for borders, #4B669B for secondary text, #CC5500 as an accent and #012B7F for hover and pressed states. For a palette, the analogous pair #08D6FE and #3008FE stays calm, while #FEAB08 is the loudest partner.

What is #085bfe in CMYK for printing?

cmyk(97%, 64%, 0%, 0%). 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 #085bfe warm or cool?

Cool — it scores 95 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #1008FE; nudged cooler, #005EED.

Which Tailwind color is closest to #085bfe?

The indigo family — its 500 step is #6366f1, ΔE2000 6.9 away. That is a visible difference, so define #085bfe as a custom token rather than reaching for the built-in.

How do I use #085bfe in Tailwind CSS?

Inline it as an arbitrary value with bg-[#085bfe] or text-[#085bfe], 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 #085bfe with 50% opacity?

rgba(8, 91, 254, 0.5), or #085bfe80 in eight-digit hex. Over white that composites to #84ADFF; over black, #042E7F.

Is #085bfe a web-safe color?

No. The nearest web-safe colour is #0066FF, ΔE2000 3.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #085bfe mean?

As a blue, it reads trusted, calm, competent. 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 effect is amplified — it will dominate whatever sits beside it.

What gradient works with #085bfe?

The safest is same-hue elevation: linear-gradient(135deg, #4583FE, #085bfe 45%, #012B7F). For more colour, a short hue run to #6001E7 keeps it rich without turning muddy.
