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 #7abcd8

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
  • Thin strokes and 1px borders — they disappear on light UI
  • 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 #1D4E63
Safe as a 1px border on white
No — use #3F9EC7

Meaning and mood

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

cleantechnicalfreshclinical

Cyan reads as water, air and infrastructure: cool, hygienic, engineered.

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

At high lightness it disappears into white surfaces and thin strokes vanish entirely.

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.

#7abcd8, answered

What color is #7abcd8?

#7abcd8 is a light vivid cyan, closest to Sky Blue (ΔE2000 4.6). It sits at 198° on the hue wheel with 55% saturation and 66% lightness, which reads as cool.

What is the RGB value of #7abcd8?

rgb(122, 188, 216) — 122 red, 188 green and 216 blue out of 255, or 47.8% / 73.7% / 84.7% by channel.

What is #7abcd8 in HSL and HSV?

hsl(198, 55%, 66%) and hsv(198, 44%, 85%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #7abcd8 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4506 and perceived brightness is 69%, so black text on it reaches 10.01:1.

Should I use black or white text on #7abcd8?

Black. It scores 10.01:1 against #7abcd8, versus 2.10:1 for white — AAA at any size.

Is #7abcd8 accessible on a white background?

#7abcd8 on white scores 2.10:1, which fails WCAG AA at every size. Darken it to #2F7D9F to reach 4.5:1, or #235E78 for 7:1.

What is the complementary color of #7abcd8?

#D8967A sits directly opposite on the wheel. Softer options are the split-complements #D87A8D and #D8C57A, which give the same contrast with far less vibration.

What colors go well with #7abcd8?

For interface work: #F4F9FA as the surface, #C0DFED for borders, #4B839B for secondary text, #A22F2A as an accent and #1D4E63 for hover and pressed states. For a palette, the analogous pair #7AD8C5 and #7A8DD8 stays calm, while #D8967A is the loudest partner.

What is #7abcd8 in CMYK for printing?

cmyk(44%, 13%, 0%, 15%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #7abcd8 warm or cool?

Cool — it scores 95 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #7AD8D2; nudged cooler, #78AEDA.

Which Tailwind color is closest to #7abcd8?

The cyan family — its 500 step is #06b6d4, ΔE2000 7.9 away. That is a visible difference, so define #7abcd8 as a custom token rather than reaching for the built-in.

How do I use #7abcd8 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#7abcd8] or text-[#7abcd8], 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 #7abcd8 with 50% opacity?

rgba(122, 188, 216, 0.5), or #7abcd880 in eight-digit hex. Over white that composites to #BDDEEC; over black, #3D5E6C.

Is #7abcd8 a web-safe color?

No. The nearest web-safe colour is #66CCCC, ΔE2000 12.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #7abcd8 mean?

As a cyan, it reads clean, technical, fresh. Cyan reads as water, air and infrastructure: cool, hygienic, engineered. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #7abcd8?

The safest is same-hue elevation: linear-gradient(135deg, #A9D4E6, #7abcd8 45%, #1D4E63). For more colour, a short hue run to #6862D1 keeps it rich without turning muddy.
