  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Full-page backgrounds — tiring over long sessions
  • 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 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 #653ce2 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.

#653ce2, answered

What color is #653ce2?

#653ce2 is a balanced vivid blue, closest to Blue Violet (ΔE2000 5.7). It sits at 255° on the hue wheel with 74% saturation and 56% lightness, which reads as cool.

What is the RGB value of #653ce2?

rgb(101, 60, 226) — 101 red, 60 green and 226 blue out of 255, or 39.6% / 23.5% / 88.6% by channel.

What is #653ce2 in HSL and HSV?

hsl(255, 74%, 56%) and hsv(255, 73%, 89%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #653ce2 a light or a dark color?

It is a dark color. Relative luminance is 0.1149 and perceived brightness is 41%, so white text on it reaches 6.37:1.

Should I use black or white text on #653ce2?

White. It scores 6.37:1 against #653ce2, versus 3.30:1 for black — AA at any size.

Is #653ce2 accessible on a white background?

#653ce2 on white scores 6.37:1, which clears AA at every size but not AAA.

What is the complementary color of #653ce2?

#B9E23C sits directly opposite on the wheel. Softer options are the split-complements #E2B83C and #66E23C, which give the same contrast with far less vibration.

What colors go well with #653ce2?

For interface work: #F6F4FA as the surface, #CBC0ED for borders, #5E4B9B for secondary text, #B5B517 as an accent and #28116F for hover and pressed states. For a palette, the analogous pair #3C66E2 and #B83CE2 stays calm, while #B9E23C is the loudest partner.

What is #653ce2 in CMYK for printing?

cmyk(55%, 74%, 0%, 11%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #653ce2 warm or cool?

Cool — it scores 75 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #A23CE2; nudged cooler, #3A4EE4.

Which Tailwind color is closest to #653ce2?

The violet family — its 500 step is #8b5cf6, ΔE2000 10.9 away. That is a visible difference, so define #653ce2 as a custom token rather than reaching for the built-in.

How do I use #653ce2 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#653ce2] or text-[#653ce2], 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 #653ce2 with 50% opacity?

rgba(101, 60, 226, 0.5), or #653ce280 in eight-digit hex. Over white that composites to #B29EF1; over black, #331E71.

Is #653ce2 a web-safe color?

No. The nearest web-safe colour is #6633CC, ΔE2000 3.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #653ce2 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 chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #653ce2?
