How to use #779ba0

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

Works well for
  • Headings from 24px up on white
  • 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
  • Small text on white — under 4.5:1
  • Thin strokes and 1px borders — they disappear on light UI
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
24px / 18.66px bold
Safe as a fill behind white type
No — use #34484B
Safe as a 1px border on white
Yes

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.

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

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.

#779ba0, answered

What color is #779ba0?

#779ba0 is a balanced soft cyan, closest to Cadet Blue (ΔE2000 6.1). It sits at 187° on the hue wheel with 18% saturation and 55% lightness, which reads as cool.

What is the RGB value of #779ba0?

rgb(119, 155, 160) — 119 red, 155 green and 160 blue out of 255, or 46.7% / 60.8% / 62.7% by channel.

What is #779ba0 in HSL and HSV?

hsl(187, 18%, 55%) and hsv(187, 26%, 63%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #779ba0 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2990 and perceived brightness is 57%, so black text on it reaches 6.98:1.

Should I use black or white text on #779ba0?

Black. It scores 6.98:1 against #779ba0, versus 3.01:1 for white — AA at any size.

Is #779ba0 accessible on a white background?

#779ba0 on white scores 3.01:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #5A7B80 to reach 4.5:1, or #435C5F for 7:1.

What is the complementary color of #779ba0?

#A07C77 sits directly opposite on the wheel. Softer options are the split-complements #A07787 and #A09077, which give the same contrast with far less vibration.

What colors go well with #779ba0?

For interface work: #F6F8F9 as the surface, #CFDCDD for borders, #5E8287 for secondary text, #A57279 as an accent and #34484B for hover and pressed states. For a palette, the analogous pair #77A090 and #7787A0 stays calm, while #A07C77 is the loudest partner.

What is #779ba0 in CMYK for printing?

cmyk(26%, 3%, 0%, 37%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #779ba0 warm or cool?

Cool — it scores 71 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #77A096; nudged cooler, #758DA2.

Which Tailwind color is closest to #779ba0?

The cyan family — its 500 step is #06b6d4, ΔE2000 13.4 away. That is a visible difference, so define #779ba0 as a custom token rather than reaching for the built-in.

How do I use #779ba0 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#779ba0] or text-[#779ba0], 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 #779ba0 with 50% opacity?

rgba(119, 155, 160, 0.5), or #779ba080 in eight-digit hex. Over white that composites to #BBCDD0; over black, #3C4E50.

Is #779ba0 a web-safe color?
