}Best text color
Only one of black and white can be right. This is the one, with the number that proves it.
Make it accessible
A contrast checker tells you that you failed. This tells you what to ship instead — same hue, same saturation, lightness moved only as far as WCAG demands.
Large text — 24px regular or 18.66px bold and above — only needs 3:1, so #B15ABC is enough for headings on white. Non-text elements such as icons, chart strokes and focus rings also sit at 3:1 under WCAG 2.2 (1.4.11).
Accessibility — WCAG contrast
Contrast is symmetric, so each row covers both directions: #b15abc as text on that neutral, and that neutral as text on #b15abc.

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.
Color scale — 50 to 950
A Tailwind-shaped ramp built around this exact hex. #b15abc is pinned to step 500; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.
The same eleven steps expressed in OKLCH, where equal lightness numbers actually look equally spaced. HSL ramps go muddy in the yellows and washed out in the blues; this one does not. Modern browsers render it natively — the hex ramp above is the fallback.

Meaning and mood
What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.
Pink is the fastest way to signal that a product is not another enterprise dashboard. It carries beauty, fashion and culture brands.
The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. The mid lightness keeps it versatile in both themes.
Strong gendered associations in some markets — test it with the audience you actually have.

#b15abc, answered
What color is #b15abc?
#b15abc is a balanced soft magenta / pink, closest to Medium Orchid (ΔE2000 4). It sits at 293° on the hue wheel with 42% saturation and 55% lightness, which reads as neutral.
What is the RGB value of #b15abc?
rgb(177, 90, 188) — 177 red, 90 green and 188 blue out of 255, or 69.4% / 35.3% / 73.7% by channel.
What is #b15abc in HSL and HSV?
hsl(293, 42%, 55%) and hsv(293, 52%, 74%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.
Is #b15abc a light or a dark color?
It is a mid-tone. Relative luminance is 0.2029 and perceived brightness is 53%, so black text on it reaches 5.06:1.
Should I use black or white text on #b15abc?
Black. It scores 5.06:1 against #b15abc, versus 4.15:1 for white — AA at any size.
Is #b15abc accessible on a white background?
#b15abc on white scores 4.15:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #AC4FB8 to reach 4.5:1, or #82398C for 7:1.
What is the complementary color of #b15abc?
#65BC5A sits directly opposite on the wheel. Softer options are the split-complements #96BC5A and #5ABC80, which give the same contrast with far less vibration.
What colors go well with #b15abc?
For interface work: #FAF4FA as the surface, #E4C5E7 for borders, #924B9B for secondary text, #599636 as an accent and #55255B for hover and pressed states. For a palette, the analogous pair #805ABC and #BC5A96 stays calm, while #65BC5A is the loudest partner.
What is #b15abc in CMYK for printing?
cmyk(6%, 52%, 0%, 26%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.
Is #b15abc warm or cool?
Neutral — it scores 54 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #BC5AA3; nudged cooler, #8D58BE.
Which Tailwind color is closest to #b15abc?
The fuchsia family — its 500 step is #d946ef, ΔE2000 9 away. That is a visible difference, so define #b15abc as a custom token rather than reaching for the built-in.
How do I use #b15abc in Tailwind CSS?
Inline it as an arbitrary value with bg-[#b15abc] or text-[#b15abc], 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 #b15abc with 50% opacity?
rgba(177, 90, 188, 0.5), or #b15abc80 in eight-digit hex. Over white that composites to #D8ADDE; over black, #592D5E.
Is #b15abc a web-safe color?
No. The nearest web-safe colour is #9966CC, ΔE2000 7 away. The palette only matters for legacy displays and some email clients now.
What does the color #b15abc 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 moderate chroma the association is present but not shouted.
What gradient works with #b15abc?
The safest is same-hue elevation: linear-gradient(135deg, #C686CE, #b15abc 45%, #55255B). For more colour, a short hue run to #B0476D keeps it rich without turning muddy.
