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.

What each alpha value actually composites to. The top row is #47496e 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.

#47496e is a dark soft blue, closest to Dark Slate Blue (ΔE2000 9). It sits at 237° on the hue wheel with 22% saturation and 36% lightness, which reads as cool.

What is the RGB value of #47496e?

rgb(71, 73, 110) — 71 red, 73 green and 110 blue out of 255, or 27.8% / 28.6% / 43.1% by channel.

What is #47496e in HSL and HSV?

hsl(237, 22%, 36%) and hsv(237, 35%, 43%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

It is a dark color. Relative luminance is 0.0723 and perceived brightness is 30%, so white text on it reaches 8.59:1.

Should I use black or white text on #47496e?

White. It scores 8.59:1 against #47496e, versus 2.45:1 for black — AAA at any size.

What colors go well with #47496e?

For interface work: #F6F6F9 as the surface, #CDCEDF for borders, #5A5D8B for secondary text, #726443 as an accent and #32334D for hover and pressed states. For a palette, the analogous pair #475D6E and #59476E stays calm, while #6E6C47 is the loudest partner.

Which Tailwind color is closest to #47496e?

The slate family — its 500 step is #64748b, ΔE2000 16.7 away. That is a visible difference, so define #47496e as a custom token rather than reaching for the built-in.

How do I use #47496e in Tailwind CSS?

Inline it as an arbitrary value with bg-[#47496e] or text-[#47496e], 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 #47496e with 50% opacity?

rgba(71, 73, 110, 0.5), or #47496e80 in eight-digit hex. Over white that composites to #A3A4B7; over black, #242537.

Is #47496e a web-safe color?
