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 #7bb4df

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 #194567
Safe as a 1px border on white
No — use #4E9AD4

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The lightness keeps it airy and approachable.

Worth knowing

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

Transparency

What each alpha value actually composites to. The top row is #7bb4df 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.

#7bb4df, answered

What color is #7bb4df?

#7bb4df is a light vivid blue, closest to Light Sky Blue (ΔE2000 6.8). It sits at 206° on the hue wheel with 61% saturation and 68% lightness, which reads as cool.

What is the RGB value of #7bb4df?

rgb(123, 180, 223) — 123 red, 180 green and 223 blue out of 255, or 48.2% / 70.6% / 87.5% by channel.

What is #7bb4df in HSL and HSV?

hsl(206, 61%, 68%) and hsv(206, 45%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #7bb4df a light or a dark color?

It is a mid-tone. Relative luminance is 0.4218 and perceived brightness is 67%, so black text on it reaches 9.44:1.

Should I use black or white text on #7bb4df?

Black. It scores 9.44:1 against #7bb4df, versus 2.23:1 for white — AAA at any size.

Is #7bb4df accessible on a white background?

#7bb4df on white scores 2.23:1, which fails WCAG AA at every size. Darken it to #2C79B4 to reach 4.5:1, or #215B87 for 7:1.

What is the complementary color of #7bb4df?

#DFA67B sits directly opposite on the wheel. Softer options are the split-complements #DF7B82 and #DFD87B, which give the same contrast with far less vibration.

What colors go well with #7bb4df?

For interface work: #F4F8FA as the surface, #C0D9ED for borders, #4B789B for secondary text, #A83C24 as an accent and #194567 for hover and pressed states. For a palette, the analogous pair #7BDFD8 and #7B82DF stays calm, while #DFA67B is the loudest partner.

What is #7bb4df in CMYK for printing?

cmyk(45%, 19%, 0%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #7bb4df warm or cool?

Cool — it scores 98 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #7B8FDF; nudged cooler, #64A1DC.

Which Tailwind color is closest to #7bb4df?

The sky family — its 500 step is #0ea5e9, ΔE2000 8.3 away. That is a visible difference, so define #7bb4df as a custom token rather than reaching for the built-in.

How do I use #7bb4df in Tailwind CSS?

Inline it as an arbitrary value with bg-[#7bb4df] or text-[#7bb4df], 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 #7bb4df with 50% opacity?

rgba(123, 180, 223, 0.5), or #7bb4df80 in eight-digit hex. Over white that composites to #BDDAEF; over black, #3E5A70.

Is #7bb4df a web-safe color?

No. The nearest web-safe colour is #66CCCC, ΔE2000 18.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #7bb4df 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 #7bb4df?
