  • 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.

#0844fe, answered

What color is #0844fe?

#0844fe is a balanced electric blue, closest to Blue (ΔE2000 9.1). It sits at 225° on the hue wheel with 99% saturation and 51% lightness, which reads as cool.

What is the RGB value of #0844fe?

rgb(8, 68, 254) — 8 red, 68 green and 254 blue out of 255, or 3.1% / 26.7% / 99.6% by channel.

What is #0844fe in HSL and HSV?

hsl(225, 99%, 51%) and hsv(225, 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 #0844fe a light or a dark color?

It is a dark color. Relative luminance is 0.1134 and perceived brightness is 39%, so white text on it reaches 6.43:1.

Should I use black or white text on #0844fe?

White. It scores 6.43:1 against #0844fe, versus 3.27:1 for black — AA at any size.

Is #0844fe accessible on a white background?

#0844fe on white scores 6.43:1, which clears AA at every size but not AAA.

What is the complementary color of #0844fe?

#FEC208 sits directly opposite on the wheel. Softer options are the split-complements #FE4708 and #BFFE08, which give the same contrast with far less vibration.

What colors go well with #0844fe?

For interface work: #F4F6FA as the surface, #C0CBED for borders, #4B5E9B for secondary text, #CC6800 as an accent and #011F7F for hover and pressed states. For a palette, the analogous pair #08BFFE and #4708FE stays calm, while #FEC208 is the loudest partner.

What is #0844fe in CMYK for printing?

cmyk(97%, 73%, 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 #0844fe warm or cool?

Cool — it scores 91 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #2608FE; nudged cooler, #075CFF.

Which Tailwind color is closest to #0844fe?

The indigo family — its 500 step is #6366f1, ΔE2000 10.7 away. That is a visible difference, so define #0844fe as a custom token rather than reaching for the built-in.

How do I use #0844fe in Tailwind CSS?

Inline it as an arbitrary value with bg-[#0844fe] or text-[#0844fe], 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 #0844fe with 50% opacity?

rgba(8, 68, 254, 0.5), or #0844fe80 in eight-digit hex. Over white that composites to #84A2FF; over black, #04227F.

Is #0844fe a web-safe color?

No. The nearest web-safe colour is #0033FF, ΔE2000 3.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #0844fe 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 #0844fe?

The safest is same-hue elevation: linear-gradient(135deg, #4572FE, #0844fe 45%, #011F7F). For more colour, a short hue run to #7501E7 keeps it rich without turning muddy.
