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.

#2f013f, answered

What color is #2f013f?

#2f013f is a deep electric violet, closest to Indigo (ΔE2000 12.1). It sits at 285° on the hue wheel with 97% saturation and 13% lightness, which reads as cool.

What is the RGB value of #2f013f?

rgb(47, 1, 63) — 47 red, 1 green and 63 blue out of 255, or 18.4% / 0.4% / 24.7% by channel.

What is #2f013f in HSL and HSV?

hsl(285, 97%, 13%) and hsv(285, 98%, 25%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #2f013f a light or a dark color?

It is a dark color. Relative luminance is 0.0098 and perceived brightness is 13%, so white text on it reaches 17.54:1.

Should I use black or white text on #2f013f?

White. It scores 17.54:1 against #2f013f, versus 1.20:1 for black — AAA at any size.

Is #2f013f accessible on a white background?

#2f013f on white scores 17.54:1, which clears AAA at every size.

What is the complementary color of #2f013f?

#113F01 sits directly opposite on the wheel. Softer options are the split-complements #303F01 and #013F10, which give the same contrast with far less vibration.

What colors go well with #2f013f?

For interface work: #F9F4FA as the surface, #E1C0ED for borders, #864B9B for secondary text, #204000 as an accent and #5E027E for hover and pressed states. For a palette, the analogous pair #10013F and #3F0130 stays calm, while #113F01 is the loudest partner.

What is #2f013f in CMYK for printing?

cmyk(25%, 98%, 0%, 75%). 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 #2f013f 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 #3F0138; nudged cooler, #18003F.

Which Tailwind color is closest to #2f013f?

The gray family — its 500 step is #6b7280, ΔE2000 34.6 away. That is a visible difference, so define #2f013f as a custom token rather than reaching for the built-in.

How do I use #2f013f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#2f013f] or text-[#2f013f], 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 #2f013f with 50% opacity?

rgba(47, 1, 63, 0.5), or #2f013f80 in eight-digit hex. Over white that composites to #97809F; over black, #180120.

Is #2f013f a web-safe color?

No. The nearest web-safe colour is #330033, ΔE2000 4.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #2f013f mean?
