}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 #4798E5 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: #b2d4f4 as text on that neutral, and that neutral as text on #b2d4f4.

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. #b2d4f4 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.

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 lightness keeps it airy and approachable.
It is also the most crowded hue on the web. Distinctiveness has to come from your other choices.

#b2d4f4, answered
What color is #b2d4f4?
#b2d4f4 is a light electric blue, closest to Light Steel Blue (ΔE2000 5.2). It sits at 209° on the hue wheel with 75% saturation and 83% lightness, which reads as cool.
What is the RGB value of #b2d4f4?
rgb(178, 212, 244) — 178 red, 212 green and 244 blue out of 255, or 69.8% / 83.1% / 95.7% by channel.
What is #b2d4f4 in HSL and HSV?
hsl(209, 75%, 83%) and hsv(209, 27%, 96%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.
Is #b2d4f4 a light or a dark color?
It is a light color. Relative luminance is 0.6308 and perceived brightness is 81%, so black text on it reaches 13.62:1.
Should I use black or white text on #b2d4f4?
Black. It scores 13.62:1 against #b2d4f4, versus 1.54:1 for white — AAA at any size.
Is #b2d4f4 accessible on a white background?
#b2d4f4 on white scores 1.54:1, which fails WCAG AA at every size. Darken it to #1D77CC to reach 4.5:1, or #165A9B for 7:1.
What is the complementary color of #b2d4f4?
#F4D2B2 sits directly opposite on the wheel. Softer options are the split-complements #F4B2B3 and #F4F3B2, which give the same contrast with far less vibration.
What colors go well with #b2d4f4?
For interface work: #F4F7FA as the surface, #C0D7ED for borders, #4B749B for secondary text, #B73A15 as an accent and #104170 for hover and pressed states. For a palette, the analogous pair #B2F4F3 and #B2B3F4 stays calm, while #F4D2B2 is the loudest partner.
What is #b2d4f4 in CMYK for printing?
cmyk(27%, 13%, 0%, 4%). 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 #b2d4f4 warm or cool?
Cool — it scores 100 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B2BCF4; nudged cooler, #9AC5F2.
Which Tailwind color is closest to #b2d4f4?
The cyan family — its 500 step is #06b6d4, ΔE2000 17.8 away. That is a visible difference, so define #b2d4f4 as a custom token rather than reaching for the built-in.
How do I use #b2d4f4 in Tailwind CSS?
Inline it as an arbitrary value with bg-[#b2d4f4] or text-[#b2d4f4], 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 #b2d4f4 with 50% opacity?
rgba(178, 212, 244, 0.5), or #b2d4f480 in eight-digit hex. Over white that composites to #D9EAFA; over black, #596A7A.
Is #b2d4f4 a web-safe color?
No. The nearest web-safe colour is #99CCFF, ΔE2000 5 away. The palette only matters for legacy displays and some email clients now.
What does the color #b2d4f4 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 #b2d4f4?
The safest is same-hue elevation: linear-gradient(135deg, #E7F2FC, #b2d4f4 45%, #104170). For more colour, a short hue run to #AC97F0 keeps it rich without turning muddy.
