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 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 #5f48af 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.

#5f48af, answered

What color is #5f48af?

#5f48af is a balanced soft blue, closest to Rebecca Purple (ΔE2000 6.9). It sits at 253° on the hue wheel with 42% saturation and 48% lightness, which reads as cool.

What is the RGB value of #5f48af?

rgb(95, 72, 175) — 95 red, 72 green and 175 blue out of 255, or 37.3% / 28.2% / 68.6% by channel.

What is #5f48af in HSL and HSV?

hsl(253, 42%, 48%) and hsv(253, 59%, 69%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #5f48af a light or a dark color?

It is a dark color. Relative luminance is 0.1016 and perceived brightness is 38%, so white text on it reaches 6.92:1.

Should I use black or white text on #5f48af?

White. It scores 6.92:1 against #5f48af, versus 3.03:1 for black — AA at any size.

Is #5f48af accessible on a white background?

#5f48af on white scores 6.92:1, which clears AA at every size but not AAA.

What is the complementary color of #5f48af?

#98AF48 sits directly opposite on the wheel. Softer options are the split-complements #AF9248 and #64AF48, which give the same contrast with far less vibration.

What colors go well with #5f48af?

For interface work: #F6F4FA as the surface, #CDC5E7 for borders, #5D4B9B for secondary text, #959237 as an accent and #31255A for hover and pressed states. For a palette, the analogous pair #4864AF and #9248AF stays calm, while #98AF48 is the loudest partner.

What is #5f48af in CMYK for printing?

cmyk(46%, 59%, 0%, 31%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #5f48af warm or cool?

Cool — it scores 76 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #8548AF; nudged cooler, #4555B1.

Which Tailwind color is closest to #5f48af?

The indigo family — its 500 step is #6366f1, ΔE2000 13.3 away. That is a visible difference, so define #5f48af as a custom token rather than reaching for the built-in.

How do I use #5f48af in Tailwind CSS?

Inline it as an arbitrary value with bg-[#5f48af] or text-[#5f48af], 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 #5f48af with 50% opacity?

rgba(95, 72, 175, 0.5), or #5f48af80 in eight-digit hex. Over white that composites to #AFA4D7; over black, #302458.

Is #5f48af a web-safe color?

No. The nearest web-safe colour is #663399, ΔE2000 6.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #5f48af mean?

As a blue, it reads trusted, calm, competent. The default of institutions for a reason: blue is read as stable and safe across nearly every culture that has been surveyed. At this moderate chroma the association is present but not shouted.

What gradient works with #5f48af?

The safest is same-hue elevation: linear-gradient(135deg, #8370C4, #5f48af 45%, #31255A). For more colour, a short hue run to #973F99 keeps it rich without turning muddy.
