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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. 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 #620487 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.

#620487, answered

What color is #620487?

#620487 is a dark electric violet, closest to Indigo (ΔE2000 4.3). It sits at 283° on the hue wheel with 94% saturation and 27% lightness, which reads as cool.

What is the RGB value of #620487?

rgb(98, 4, 135) — 98 red, 4 green and 135 blue out of 255, or 38.4% / 1.6% / 52.9% by channel.

What is #620487 in HSL and HSV?

hsl(283, 94%, 27%) and hsv(283, 97%, 53%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #620487 a light or a dark color?

It is a dark color. Relative luminance is 0.0443 and perceived brightness is 28%, so white text on it reaches 11.13:1.

Should I use black or white text on #620487?

White. It scores 11.13:1 against #620487, versus 1.89:1 for black — AAA at any size.

Is #620487 accessible on a white background?

#620487 on white scores 11.13:1, which clears AAA at every size.

What is the complementary color of #620487?

#298704 sits directly opposite on the wheel. Softer options are the split-complements #6B8704 and #048721, which give the same contrast with far less vibration.

What colors go well with #620487?

For interface work: #F9F4FA as the surface, #E0C0ED for borders, #844B9B for secondary text, #4A8A01 as an accent and #5A047C for hover and pressed states. For a palette, the analogous pair #210487 and #87046B stays calm, while #298704 is the loudest partner.

What is #620487 in CMYK for printing?

cmyk(27%, 97%, 0%, 47%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #620487 warm or cool?

Cool — it scores 59 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #87047C; nudged cooler, #320389.

Which Tailwind color is closest to #620487?

The violet family — its 500 step is #8b5cf6, ΔE2000 24.6 away. That is a visible difference, so define #620487 as a custom token rather than reaching for the built-in.

How do I use #620487 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#620487] or text-[#620487], 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 #620487 with 50% opacity?

rgba(98, 4, 135, 0.5), or #62048780 in eight-digit hex. Over white that composites to #B182C3; over black, #310244.

Is #620487 a web-safe color?
