  • 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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. 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.

What each alpha value actually composites to. The top row is #14166f 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.

#14166f, answered

What color is #14166f?

#14166f is a dark vivid blue — the CSS keyword Midnight Blue. It sits at 239° on the hue wheel with 70% saturation and 26% lightness, which reads as cool.

What is the RGB value of #14166f?

rgb(20, 22, 111) — 20 red, 22 green and 111 blue out of 255, or 7.8% / 8.6% / 43.5% by channel.

What is #14166f in HSL and HSV?

hsl(239, 70%, 26%) and hsv(239, 82%, 44%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #14166f a light or a dark color?

It is a dark color. Relative luminance is 0.0187 and perceived brightness is 17%, so white text on it reaches 15.28:1.

Should I use black or white text on #14166f?

White. It scores 15.28:1 against #14166f, versus 1.37:1 for black — AAA at any size.

Is #14166f accessible on a white background?

#14166f on white scores 15.28:1, which clears AAA at every size.

What is the complementary color of #14166f?

#6F6D14 sits directly opposite on the wheel. Softer options are the split-complements #6F4014 and #446F14, which give the same contrast with far less vibration.

What colors go well with #14166f?

For interface work: #F4F4FA as the surface, #C0C1ED for borders, #4B4C9B for secondary text, #725811 as an accent and #13156C for hover and pressed states. For a palette, the analogous pair #14446F and #40146F stays calm, while #6F6D14 is the loudest partner.

What is #14166f in CMYK for printing?

cmyk(82%, 80%, 0%, 57%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #14166f warm or cool?

Cool — it scores 84 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #33146F; nudged cooler, #133170.

Which Tailwind color is closest to #14166f?

The slate family — its 500 step is #64748b, ΔE2000 28.9 away. That is a visible difference, so define #14166f as a custom token rather than reaching for the built-in.

How do I use #14166f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#14166f] or text-[#14166f], 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 #14166f with 50% opacity?

rgba(20, 22, 111, 0.5), or #14166f80 in eight-digit hex. Over white that composites to #8A8BB7; over black, #0A0B38.

Is #14166f a web-safe color?
