  • 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.

Transparency

What each alpha value actually composites to. The top row is #192546 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.

#192546, answered

What color is #192546?

#192546 is a deep vivid blue, closest to Midnight Blue (ΔE2000 10.8). It sits at 224° on the hue wheel with 47% saturation and 19% lightness, which reads as cool.

What is the RGB value of #192546?

rgb(25, 37, 70) — 25 red, 37 green and 70 blue out of 255, or 9.8% / 14.5% / 27.5% by channel.

What is #192546 in HSL and HSV?

hsl(224, 47%, 19%) and hsv(224, 64%, 27%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #192546 a light or a dark color?

It is a dark color. Relative luminance is 0.0197 and perceived brightness is 15%, so white text on it reaches 15.06:1.

Should I use black or white text on #192546?

White. It scores 15.06:1 against #192546, versus 1.39:1 for black — AAA at any size.

Is #192546 accessible on a white background?

#192546 on white scores 15.06:1, which clears AAA at every size.

What is the complementary color of #192546?

#463A19 sits directly opposite on the wheel. Softer options are the split-complements #462319 and #3B4619, which give the same contrast with far less vibration.

What colors go well with #192546?

For interface work: #F4F6FA as the surface, #C3CDEA for borders, #4B609B for secondary text, #482F17 as an accent and #22325E for hover and pressed states. For a palette, the analogous pair #193B46 and #231946 stays calm, while #463A19 is the loudest partner.

What is #192546 in CMYK for printing?

cmyk(64%, 47%, 0%, 73%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #192546 warm or cool?

Cool — it scores 92 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #1D1946; nudged cooler, #182C47.

Which Tailwind color is closest to #192546?

The slate family — its 500 step is #64748b, ΔE2000 27 away. That is a visible difference, so define #192546 as a custom token rather than reaching for the built-in.

How do I use #192546 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#192546] or text-[#192546], 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 #192546 with 50% opacity?

rgba(25, 37, 70, 0.5), or #19254680 in eight-digit hex. Over white that composites to #8C92A3; over black, #0D1323.

Is #192546 a web-safe color?
