How to use #73b2c2

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
  • 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 #274F59
Safe as a 1px border on white
No — use #509EB3

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.

What each alpha value actually composites to. The top row is #73b2c2 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.

#73b2c2, answered

What color is #73b2c2?

#73b2c2 is a balanced soft cyan, closest to Sky Blue (ΔE2000 8.5). It sits at 192° on the hue wheel with 39% saturation and 61% lightness, which reads as cool.

What is the RGB value of #73b2c2?

rgb(115, 178, 194) — 115 red, 178 green and 194 blue out of 255, or 45.1% / 69.8% / 76.1% by channel.

What is #73b2c2 in HSL and HSV?

hsl(192, 39%, 61%) and hsv(192, 41%, 76%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #73b2c2 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3938 and perceived brightness is 64%, so black text on it reaches 8.88:1.

Should I use black or white text on #73b2c2?

Black. It scores 8.88:1 against #73b2c2, versus 2.37:1 for white — AAA at any size.

Is #73b2c2 accessible on a white background?

#73b2c2 on white scores 2.37:1, which fails WCAG AA at every size. Darken it to #3D7D8D to reach 4.5:1, or #2E5D69 for 7:1.

What is the complementary color of #73b2c2?

#C28373 sits directly opposite on the wheel. Softer options are the split-complements #C2738A and #C2AB73, which give the same contrast with far less vibration.

What colors go well with #73b2c2?

For interface work: #F4F9FA as the surface, #C6E0E6 for borders, #4B8B9B for secondary text, #C66F73 as an accent and #274F59 for hover and pressed states. For a palette, the analogous pair #73C2AB and #738AC2 stays calm, while #C28373 is the loudest partner.

What is #73b2c2 in CMYK for printing?

cmyk(41%, 8%, 0%, 24%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #73b2c2 warm or cool?

Cool — it scores 93 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #73C2B5; nudged cooler, #71A0C4.

Which Tailwind color is closest to #73b2c2?

The cyan family — its 500 step is #06b6d4, ΔE2000 7 away. That is a visible difference, so define #73b2c2 as a custom token rather than reaching for the built-in.

How do I use #73b2c2 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#73b2c2] or text-[#73b2c2], 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 #73b2c2 with 50% opacity?

rgba(115, 178, 194, 0.5), or #73b2c280 in eight-digit hex. Over white that composites to #B9D9E1; over black, #3A5961.
