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 #75dfbd

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 #18684E
Safe as a 1px border on white
No — use #26A47C

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.

Transparency

What each alpha value actually composites to. The top row is #75dfbd 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.

#75dfbd, answered

What color is #75dfbd?

#75dfbd is a light vivid cyan, closest to Medium Aqua Marine (ΔE2000 4.4). It sits at 161° on the hue wheel with 62% saturation and 67% lightness, which reads as cool.

What is the RGB value of #75dfbd?

rgb(117, 223, 189) — 117 red, 223 green and 189 blue out of 255, or 45.9% / 87.5% / 74.1% by channel.

What is #75dfbd in HSL and HSV?

hsl(161, 62%, 67%) and hsv(161, 48%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #75dfbd a light or a dark color?

It is a light color. Relative luminance is 0.6023 and perceived brightness is 76%, so black text on it reaches 13.05:1.

Should I use black or white text on #75dfbd?

Black. It scores 13.05:1 against #75dfbd, versus 1.61:1 for white — AAA at any size.

Is #75dfbd accessible on a white background?

#75dfbd on white scores 1.61:1, which fails WCAG AA at every size. Darken it to #1E8363 to reach 4.5:1, or #17624A for 7:1.

What is the complementary color of #75dfbd?

#DF7597 sits directly opposite on the wheel. Softer options are the split-complements #DF75CC and #DF8875, which give the same contrast with far less vibration.

What colors go well with #75dfbd?

For interface work: #F4FAF8 as the surface, #C0EDDE for borders, #4B9B81 for secondary text, #A92370 as an accent and #18684E for hover and pressed states. For a palette, the analogous pair #75DF88 and #75CCDF stays calm, while #DF7597 is the loudest partner.

What is #75dfbd in CMYK for printing?

cmyk(48%, 0%, 15%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #75dfbd warm or cool?

Cool — it scores 79 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #75DF96; nudged cooler, #73DCE1.

Which Tailwind color is closest to #75dfbd?

The teal family — its 500 step is #14b8a6, ΔE2000 12.1 away. That is a visible difference, so define #75dfbd as a custom token rather than reaching for the built-in.

How do I use #75dfbd in Tailwind CSS?

Inline it as an arbitrary value with bg-[#75dfbd] or text-[#75dfbd], 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 #75dfbd with 50% opacity?

rgba(117, 223, 189, 0.5), or #75dfbd80 in eight-digit hex. Over white that composites to #BAEFDE; over black, #3B705F.

Is #75dfbd a web-safe color?

No. The nearest web-safe colour is #66CCCC, ΔE2000 12.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #75dfbd 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 #75dfbd?
