At a glance
Every number on this page in one read: what #c4bcfc is made of, how bright it looks, and which way it leans.

}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 #9182F9 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: #c4bcfc as text on that neutral, and that neutral as text on #c4bcfc.

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. #c4bcfc is pinned to step 200; 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.

Not a palette — a role sheet. Each swatch answers one question you will hit while building the component.
Surface, border, heading and body all derive from this one hue, so the screen stays coherent without a second palette.
Lightness flips, hue holds. The accent stays the anchor in both themes.

Meaning and mood
What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.
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 association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. The high lightness makes it recede — a surface colour rather than a statement.
It is also the most crowded hue on the web. Distinctiveness has to come from your other choices.

#c4bcfc, answered
What color is #c4bcfc?
#c4bcfc is a pale electric blue, closest to Light Steel Blue (ΔE2000 10.3). It sits at 248° on the hue wheel with 91% saturation and 86% lightness, which reads as cool.
What is the RGB value of #c4bcfc?
rgb(196, 188, 252) — 196 red, 188 green and 252 blue out of 255, or 76.9% / 73.7% / 98.8% by channel.
What is #c4bcfc in HSL and HSV?
hsl(248, 91%, 86%) and hsv(248, 25%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.
Is #c4bcfc a light or a dark color?
It is a light color. Relative luminance is 0.5473 and perceived brightness is 78%, so black text on it reaches 11.95:1.
Should I use black or white text on #c4bcfc?
Black. It scores 11.95:1 against #c4bcfc, versus 1.76:1 for white — AAA at any size.
Is #c4bcfc accessible on a white background?
#c4bcfc on white scores 1.76:1, which fails WCAG AA at every size. Darken it to #6E5BF8 to reach 4.5:1, or #432AF5 for 7:1.
What is the complementary color of #c4bcfc?
#F4FCBC sits directly opposite on the wheel. Softer options are the split-complements #FCE4BC and #D4FCBC, which give the same contrast with far less vibration.
What colors go well with #c4bcfc?
For interface work: #F5F4FA as the surface, #C5C0ED for borders, #554B9B for secondary text, #C6AF06 as an accent and #14057A for hover and pressed states. For a palette, the analogous pair #BCD4FC and #E4BCFC stays calm, while #F4FCBC is the loudest partner.
What is #c4bcfc in CMYK for printing?
cmyk(22%, 25%, 0%, 1%). 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 #c4bcfc warm or cool?
Cool — it scores 79 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #DCBCFC; nudged cooler, #BBCBFD.
Which Tailwind color is closest to #c4bcfc?
The blue family — its 500 step is #3b82f6, ΔE2000 24.6 away. That is a visible difference, so define #c4bcfc as a custom token rather than reaching for the built-in.
How do I use #c4bcfc in Tailwind CSS?
Inline it as an arbitrary value with bg-[#c4bcfc] or text-[#c4bcfc], 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 #c4bcfc with 50% opacity?
rgba(196, 188, 252, 0.5), or #c4bcfc80 in eight-digit hex. Over white that composites to #E2DEFE; over black, #625E7E.
Is #c4bcfc a web-safe color?
No. The nearest web-safe colour is #CCCCFF, ΔE2000 4.4 away. The palette only matters for legacy displays and some email clients now.
What does the color #c4bcfc 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 #c4bcfc?
The safest is same-hue elevation: linear-gradient(135deg, #EEEBFE, #c4bcfc 45%, #14057A). For more colour, a short hue run to #EF9FFB keeps it rich without turning muddy.
