Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

creativepremiummodernimaginative

Violet sits between the warmth of red and the calm of blue, so it reads as inventive without reading as risky. Current shorthand for software craft.

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

Deep violets swallow detail on screens with poor gamma; check it on a cheap laptop panel.

Transparency

What each alpha value actually composites to. The top row is #635382 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.

#635382, answered

What color is #635382?

#635382 is a dark soft violet, closest to Dark Slate Blue (ΔE2000 10.2). It sits at 260° on the hue wheel with 22% saturation and 42% lightness, which reads as cool.

What is the RGB value of #635382?

rgb(99, 83, 130) — 99 red, 83 green and 130 blue out of 255, or 38.8% / 32.5% / 51% by channel.

What is #635382 in HSL and HSV?

hsl(260, 22%, 42%) and hsv(260, 36%, 51%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #635382 a light or a dark color?

It is a dark color. Relative luminance is 0.1045 and perceived brightness is 37%, so white text on it reaches 6.80:1.

Should I use black or white text on #635382?

White. It scores 6.80:1 against #635382, versus 3.09:1 for black — AA at any size.

Is #635382 accessible on a white background?

#635382 on white scores 6.80:1, which clears AA at every size but not AAA.

What is the complementary color of #635382?

#728253 sits directly opposite on the wheel. Softer options are the split-complements #827B53 and #5B8253, which give the same contrast with far less vibration.

What colors go well with #635382?

For interface work: #F7F6F9 as the surface, #D3CDDF for borders, #6B598C for secondary text, #81864F as an accent and #3B324E for hover and pressed states. For a palette, the analogous pair #535B82 and #7B5382 stays calm, while #728253 is the loudest partner.

What is #635382 in CMYK for printing?

cmyk(24%, 36%, 0%, 49%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #635382 warm or cool?

Cool — it scores 64 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #745382; nudged cooler, #515284.

Which Tailwind color is closest to #635382?

The slate family — its 500 step is #64748b, ΔE2000 15.9 away. That is a visible difference, so define #635382 as a custom token rather than reaching for the built-in.

How do I use #635382 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#635382] or text-[#635382], 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 #635382 with 50% opacity?

rgba(99, 83, 130, 0.5), or #63538280 in eight-digit hex. Over white that composites to #B1A9C1; over black, #322A41.

Is #635382 a web-safe color?
