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 #7acffb

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 #04537C
Safe as a 1px border on white
No — use #079CE9

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 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 #7acffb 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.

#7acffb, answered

What color is #7acffb?

#7acffb is a light electric blue, closest to Light Sky Blue (ΔE2000 2). It sits at 201° on the hue wheel with 94% saturation and 73% lightness, which reads as cool.

What is the RGB value of #7acffb?

rgb(122, 207, 251) — 122 red, 207 green and 251 blue out of 255, or 47.8% / 81.2% / 98.4% by channel.

What is #7acffb in HSL and HSV?

hsl(201, 94%, 73%) and hsv(200, 51%, 98%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #7acffb a light or a dark color?

It is a light color. Relative luminance is 0.5573 and perceived brightness is 75%, so black text on it reaches 12.15:1.

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

Black. It scores 12.15:1 against #7acffb, versus 1.73:1 for white — AAA at any size.

Is #7acffb accessible on a white background?

#7acffb on white scores 1.73:1, which fails WCAG AA at every size. Darken it to #057BB8 to reach 4.5:1, or #045D8B for 7:1.

What is the complementary color of #7acffb?

#FBA67A sits directly opposite on the wheel. Softer options are the split-complements #FB7A8E and #FBE77A, which give the same contrast with far less vibration.

What colors go well with #7acffb?

For interface work: #F4F8FA as the surface, #C0DDED for borders, #4B7F9B for secondary text, #CA1302 as an accent and #04537C for hover and pressed states. For a palette, the analogous pair #7AFBE7 and #7A8EFB stays calm, while #FBA67A is the loudest partner.

What is #7acffb in CMYK for printing?

cmyk(51%, 18%, 0%, 2%). 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 #7acffb warm or cool?

Cool — it scores 96 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #7AFBF8; nudged cooler, #78C1FC.

Which Tailwind color is closest to #7acffb?

The cyan family — its 500 step is #06b6d4, ΔE2000 11.3 away. That is a visible difference, so define #7acffb as a custom token rather than reaching for the built-in.

How do I use #7acffb in Tailwind CSS?

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

rgba(122, 207, 251, 0.5), or #7acffb80 in eight-digit hex. Over white that composites to #BDE7FD; over black, #3D687E.

Is #7acffb a web-safe color?

No. The nearest web-safe colour is #66CCFF, ΔE2000 2 away. The palette only matters for legacy displays and some email clients now.

What does the color #7acffb 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 #7acffb?
