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 #4ba2bc

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
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #234F5D
Safe as a 1px border on white
No — use #459EB8

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 mid lightness keeps it versatile in both themes.

Worth knowing

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

Transparency

What each alpha value actually composites to. The top row is #4ba2bc 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.

#4ba2bc, answered

What color is #4ba2bc?

#4ba2bc is a balanced vivid cyan, closest to Cadet Blue (ΔE2000 8.8). It sits at 194° on the hue wheel with 46% saturation and 52% lightness, which reads as cool.

What is the RGB value of #4ba2bc?

rgb(75, 162, 188) — 75 red, 162 green and 188 blue out of 255, or 29.4% / 63.5% / 73.7% by channel.

What is #4ba2bc in HSL and HSV?

hsl(194, 46%, 52%) and hsv(194, 60%, 74%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #4ba2bc a light or a dark color?

It is a mid-tone. Relative luminance is 0.3097 and perceived brightness is 57%, so black text on it reaches 7.19:1.

Should I use black or white text on #4ba2bc?

Black. It scores 7.19:1 against #4ba2bc, versus 2.92:1 for white — AAA at any size.

Is #4ba2bc accessible on a white background?

#4ba2bc on white scores 2.92:1, which fails WCAG AA at every size. Darken it to #377E93 to reach 4.5:1, or #295E6E for 7:1.

What is the complementary color of #4ba2bc?

#BC654B sits directly opposite on the wheel. Softer options are the split-complements #BC4B6A and #BC9E4B, which give the same contrast with far less vibration.

What colors go well with #4ba2bc?

For interface work: #F4F9FA as the surface, #C4E0E9 for borders, #4B889B for secondary text, #C14649 as an accent and #234F5D for hover and pressed states. For a palette, the analogous pair #4BBC9E and #4B6ABC stays calm, while #BC654B is the loudest partner.

What is #4ba2bc in CMYK for printing?

cmyk(60%, 14%, 0%, 26%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #4ba2bc 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 #4BBCAD; nudged cooler, #498DBE.

Which Tailwind color is closest to #4ba2bc?

The cyan family — its 500 step is #06b6d4, ΔE2000 6.5 away. That is a visible difference, so define #4ba2bc as a custom token rather than reaching for the built-in.

How do I use #4ba2bc in Tailwind CSS?

Inline it as an arbitrary value with bg-[#4ba2bc] or text-[#4ba2bc], 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 #4ba2bc with 50% opacity?

rgba(75, 162, 188, 0.5), or #4ba2bc80 in eight-digit hex. Over white that composites to #A5D1DE; over black, #26515E.

Is #4ba2bc a web-safe color?

No. The nearest web-safe colour is #3399CC, ΔE2000 7.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #4ba2bc 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 #4ba2bc?

The safest is same-hue elevation: linear-gradient(135deg, #78B9CD, #4ba2bc 45%, #234F5D). For more colour, a short hue run to #3F41A9 keeps it rich without turning muddy.
