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 #75ddbd

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 #19664F
Safe as a 1px border on white
No — use #29A57F

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 #75ddbd 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.

#75ddbd, answered

What color is #75ddbd?

#75ddbd is a light vivid cyan, closest to Medium Aqua Marine (ΔE2000 4.2). It sits at 162° on the hue wheel with 61% saturation and 66% lightness, which reads as cool.

What is the RGB value of #75ddbd?

rgb(117, 221, 189) — 117 red, 221 green and 189 blue out of 255, or 45.9% / 86.7% / 74.1% by channel.

What is #75ddbd in HSL and HSV?

hsl(162, 61%, 66%) and hsv(162, 47%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #75ddbd a light or a dark color?

It is a light color. Relative luminance is 0.5917 and perceived brightness is 75%, so black text on it reaches 12.83:1.

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

Black. It scores 12.83:1 against #75ddbd, versus 1.64:1 for white — AAA at any size.

Is #75ddbd accessible on a white background?

#75ddbd on white scores 1.64:1, which fails WCAG AA at every size. Darken it to #218465 to reach 4.5:1, or #18634C for 7:1.

What is the complementary color of #75ddbd?

#DD7595 sits directly opposite on the wheel. Softer options are the split-complements #DD75C9 and #DD8975, which give the same contrast with far less vibration.

What colors go well with #75ddbd?

For interface work: #F4FAF9 as the surface, #C0EDDF for borders, #4B9B82 for secondary text, #A7256E as an accent and #19664F for hover and pressed states. For a palette, the analogous pair #75DD89 and #75C9DD stays calm, while #DD7595 is the loudest partner.

What is #75ddbd in CMYK for printing?

cmyk(47%, 0%, 15%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #75ddbd warm or cool?

Cool — it scores 80 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #75DD97; nudged cooler, #73D9DF.

Which Tailwind color is closest to #75ddbd?

The teal family — its 500 step is #14b8a6, ΔE2000 11.6 away. That is a visible difference, so define #75ddbd as a custom token rather than reaching for the built-in.

How do I use #75ddbd in Tailwind CSS?

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

rgba(117, 221, 189, 0.5), or #75ddbd80 in eight-digit hex. Over white that composites to #BAEEDE; over black, #3B6F5F.

Is #75ddbd a web-safe color?

No. The nearest web-safe colour is #66CCCC, ΔE2000 11.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #75ddbd 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 #75ddbd?
