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 #80abc6

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

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • 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 #284558
Safe as a 1px border on white
No — use #679BBB

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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. The mid lightness keeps it versatile in both themes.

Worth knowing

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

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.

#80abc6, answered

What color is #80abc6?

#80abc6 is a balanced soft blue, closest to Sky Blue (ΔE2000 9.8). It sits at 203° on the hue wheel with 38% saturation and 64% lightness, which reads as cool.

What is the RGB value of #80abc6?

rgb(128, 171, 198) — 128 red, 171 green and 198 blue out of 255, or 50.2% / 67.1% / 77.6% by channel.

What is #80abc6 in HSL and HSV?

hsl(203, 38%, 64%) and hsv(203, 35%, 78%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #80abc6 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3779 and perceived brightness is 64%, so black text on it reaches 8.56:1.

Should I use black or white text on #80abc6?

Black. It scores 8.56:1 against #80abc6, versus 2.45:1 for white — AAA at any size.

Is #80abc6 accessible on a white background?

#80abc6 on white scores 2.45:1, which fails WCAG AA at every size. Darken it to #457A9A to reach 4.5:1, or #345B74 for 7:1.

What is the complementary color of #80abc6?

#C69B80 sits directly opposite on the wheel. Softer options are the split-complements #C68088 and #C6BE80, which give the same contrast with far less vibration.

What colors go well with #80abc6?

For interface work: #F4F8FA as the surface, #C7DAE6 for borders, #4B7C9B for secondary text, #91473B as an accent and #284558 for hover and pressed states. For a palette, the analogous pair #80C6BE and #8088C6 stays calm, while #C69B80 is the loudest partner.

What is #80abc6 in CMYK for printing?

cmyk(35%, 14%, 0%, 22%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #80abc6 warm or cool?

Cool — it scores 97 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #80C5C6; nudged cooler, #7EA4C8.

Which Tailwind color is closest to #80abc6?

The sky family — its 500 step is #0ea5e9, ΔE2000 10 away. That is a visible difference, so define #80abc6 as a custom token rather than reaching for the built-in.

How do I use #80abc6 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#80abc6] or text-[#80abc6], 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 #80abc6 with 50% opacity?

rgba(128, 171, 198, 0.5), or #80abc680 in eight-digit hex. Over white that composites to #C0D5E3; over black, #405663.

Is #80abc6 a web-safe color?

No. The nearest web-safe colour is #9999CC, ΔE2000 15.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #80abc6 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 moderate chroma the association is present but not shouted.

What gradient works with #80abc6?

The safest is same-hue elevation: linear-gradient(135deg, #AAC7D9, #80abc6 45%, #284558). For more colour, a short hue run to #766BBC keeps it rich without turning muddy.
