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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. 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 #393549 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.

#393549, answered

#393549 is a deep soft blue, closest to Dark Slate Blue (ΔE2000 15.8). It sits at 252° on the hue wheel with 16% saturation and 25% lightness, which reads as cool.

What is the RGB value of #393549?

rgb(57, 53, 73) — 57 red, 53 green and 73 blue out of 255, or 22.4% / 20.8% / 28.6% by channel.

What is #393549 in HSL and HSV?

hsl(252, 16%, 25%) and hsv(252, 27%, 29%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #393549 a light or a dark color?

It is a dark color. Relative luminance is 0.0390 and perceived brightness is 22%, so white text on it reaches 11.80:1.

Should I use black or white text on #393549?

White. It scores 11.80:1 against #393549, versus 1.78:1 for black — AAA at any size.

Is #393549 accessible on a white background?

#393549 on white scores 11.80:1, which clears AAA at every size.

What is the complementary color of #393549?

#454935 sits directly opposite on the wheel. Softer options are the split-complements #494335 and #3B4935, which give the same contrast with far less vibration.

What colors go well with #393549?

For interface work: #F7F6F9 as the surface, #D2D0DD for borders, #686185 for secondary text, #4C4A32 as an accent and #3A364A for hover and pressed states. For a palette, the analogous pair #353B49 and #433549 stays calm, while #454935 is the loudest partner.

What is #393549 in CMYK for printing?

cmyk(22%, 27%, 0%, 71%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Cool — it scores 62 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #403549; nudged cooler, #34374A.

Which Tailwind color is closest to #393549?

The zinc family — its 500 step is #71717a, ΔE2000 21.5 away. That is a visible difference, so define #393549 as a custom token rather than reaching for the built-in.

How do I use #393549 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#393549] or text-[#393549], 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 #393549 with 50% opacity?

rgba(57, 53, 73, 0.5), or #39354980 in eight-digit hex. Over white that composites to #9C9AA4; over black, #1D1B25.
