  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Full-page backgrounds — tiring over long sessions

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.

What each alpha value actually composites to. The top row is #2467f4 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.

#2467f4, answered

What color is #2467f4?

#2467f4 is a balanced electric blue, closest to Royal Blue (ΔE2000 2.4). It sits at 221° on the hue wheel with 90% saturation and 55% lightness, which reads as cool.

What is the RGB value of #2467f4?

rgb(36, 103, 244) — 36 red, 103 green and 244 blue out of 255, or 14.1% / 40.4% / 95.7% by channel.

What is #2467f4 in HSL and HSV?

hsl(221, 90%, 55%) and hsv(221, 85%, 96%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #2467f4 a light or a dark color?

It is a dark color. Relative luminance is 0.1661 and perceived brightness is 45%, so white text on it reaches 4.86:1.

Should I use black or white text on #2467f4?

White. It scores 4.86:1 against #2467f4, versus 4.32:1 for black — AA at any size.

Is #2467f4 accessible on a white background?

#2467f4 on white scores 4.86:1, which clears AA at every size but not AAA.

What is the complementary color of #2467f4?

#F4B124 sits directly opposite on the wheel. Softer options are the split-complements #F44924 and #CFF424, which give the same contrast with far less vibration.

What colors go well with #2467f4?

For interface work: #F4F6FA as the surface, #C0CEED for borders, #4B649B for secondary text, #C75805 as an accent and #062B79 for hover and pressed states. For a palette, the analogous pair #24CFF4 and #4924F4 stays calm, while #F4B124 is the loudest partner.

What is #2467f4 in CMYK for printing?

cmyk(85%, 58%, 0%, 4%). 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 #2467f4 warm or cool?

Cool — it scores 94 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #2D24F4; nudged cooler, #0A66F5.

Which Tailwind color is closest to #2467f4?

The indigo family — its 500 step is #6366f1, ΔE2000 6.6 away. That is a visible difference, so define #2467f4 as a custom token rather than reaching for the built-in.

How do I use #2467f4 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#2467f4] or text-[#2467f4], 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 #2467f4 with 50% opacity?

rgba(36, 103, 244, 0.5), or #2467f480 in eight-digit hex. Over white that composites to #92B3FA; over black, #12347A.

Is #2467f4 a web-safe color?
