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.

How to use #bbbcfd

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • White text placed on it
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
Not as text
Safe as a fill behind white type
No — use #04057C
Safe as a 1px border on white
No — use #8586FB

Meaning and mood

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

trustedcalmcompetentcorporate

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.

Worth knowing

It is also the most crowded hue on the web. Distinctiveness has to come from your other choices.

#bbbcfd, answered

What color is #bbbcfd?

#bbbcfd is a pale electric blue, closest to Light Steel Blue (ΔE2000 8.9). It sits at 239° on the hue wheel with 94% saturation and 86% lightness, which reads as cool.

What is the RGB value of #bbbcfd?

rgb(187, 188, 253) — 187 red, 188 green and 253 blue out of 255, or 73.3% / 73.7% / 99.2% by channel.

What is #bbbcfd in HSL and HSV?

hsl(239, 94%, 86%) and hsv(239, 26%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #bbbcfd a light or a dark color?

It is a light color. Relative luminance is 0.5362 and perceived brightness is 77%, so black text on it reaches 11.72:1.

Should I use black or white text on #bbbcfd?

Black. It scores 11.72:1 against #bbbcfd, versus 1.79:1 for white — AAA at any size.

Is #bbbcfd accessible on a white background?

#bbbcfd on white scores 1.79:1, which fails WCAG AA at every size. Darken it to #5D5FFA to reach 4.5:1, or #3033F9 for 7:1.

What is the complementary color of #bbbcfd?

#FDFCBB sits directly opposite on the wheel. Softer options are the split-complements #FDDBBB and #DDFDBB, which give the same contrast with far less vibration.

What colors go well with #bbbcfd?

For interface work: #F4F4FA as the surface, #C0C0ED for borders, #4B4C9B for secondary text, #C99503 as an accent and #04057C for hover and pressed states. For a palette, the analogous pair #BBDDFD and #DBBBFD stays calm, while #FDFCBB is the loudest partner.

What is #bbbcfd in CMYK for printing?

cmyk(26%, 26%, 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 #bbbcfd warm or cool?

Cool — it scores 84 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D2BBFD; nudged cooler, #BAD2FE.

Which Tailwind color is closest to #bbbcfd?

The blue family — its 500 step is #3b82f6, ΔE2000 22.7 away. That is a visible difference, so define #bbbcfd as a custom token rather than reaching for the built-in.

How do I use #bbbcfd in Tailwind CSS?

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

rgba(187, 188, 253, 0.5), or #bbbcfd80 in eight-digit hex. Over white that composites to #DDDEFE; over black, #5E5E7F.

Is #bbbcfd a web-safe color?

No. The nearest web-safe colour is #CCCCFF, ΔE2000 4.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #bbbcfd 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 #bbbcfd?

The safest is same-hue elevation: linear-gradient(135deg, #EBEBFE, #bbbcfd 45%, #04057C). For more colour, a short hue run to #E39DFC keeps it rich without turning muddy.
