Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.

Meaning and mood

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

expressiveyouthfulwarmconfident

Pink is the fastest way to signal that a product is not another enterprise dashboard. It carries beauty, fashion and culture brands.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The low lightness adds weight and formality.

Worth knowing

Strong gendered associations in some markets — test it with the audience you actually have.

Transparency

What each alpha value actually composites to. The top row is #a11dba 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.

#a11dba, answered

What color is #a11dba?

#a11dba is a dark vivid magenta / pink, closest to Dark Orchid (ΔE2000 4). It sits at 290° on the hue wheel with 73% saturation and 42% lightness, which reads as neutral.

What is the RGB value of #a11dba?

rgb(161, 29, 186) — 161 red, 29 green and 186 blue out of 255, or 63.1% / 11.4% / 72.9% by channel.

What is #a11dba in HSL and HSV?

hsl(290, 73%, 42%) and hsv(290, 84%, 73%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a11dba a light or a dark color?

It is a dark color. Relative luminance is 0.1200 and perceived brightness is 43%, so white text on it reaches 6.18:1.

Should I use black or white text on #a11dba?

White. It scores 6.18:1 against #a11dba, versus 3.40:1 for black — AA at any size.

Is #a11dba accessible on a white background?

#a11dba on white scores 6.18:1, which clears AA at every size but not AAA.

What is the complementary color of #a11dba?

#36BA1D sits directly opposite on the wheel. Softer options are the split-complements #85BA1D and #1DBA52, which give the same contrast with far less vibration.

What colors go well with #a11dba?

For interface work: #F9F4FA as the surface, #E5C0ED for borders, #8E4B9B for secondary text, #58B418 as an accent and #5F116E for hover and pressed states. For a palette, the analogous pair #521DBA and #BA1D85 stays calm, while #36BA1D is the loudest partner.

What is #a11dba in CMYK for printing?

cmyk(13%, 84%, 0%, 27%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #a11dba warm or cool?

Neutral — it scores 55 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #BA1D9A; nudged cooler, #671BBC.

Which Tailwind color is closest to #a11dba?

The purple family — its 500 step is #a855f7, ΔE2000 14 away. That is a visible difference, so define #a11dba as a custom token rather than reaching for the built-in.

How do I use #a11dba in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a11dba] or text-[#a11dba], 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 #a11dba with 50% opacity?

rgba(161, 29, 186, 0.5), or #a11dba80 in eight-digit hex. Over white that composites to #D08EDD; over black, #510F5D.

Is #a11dba a web-safe color?

No. The nearest web-safe colour is #9933CC, ΔE2000 4.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #a11dba mean?

As a magenta / pink, it reads expressive, youthful, warm. Pink is the fastest way to signal that a product is not another enterprise dashboard. It carries beauty, fashion and culture brands. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #a11dba?

The safest is same-hue elevation: linear-gradient(135deg, #C435DF, #a11dba 45%, #5F116E). For more colour, a short hue run to #A01950 keeps it rich without turning muddy.
