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 #0bddbb

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 #067967
Safe as a 1px border on white
No — use #08A88E

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. The mid lightness keeps it versatile in both themes.

Worth knowing

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

#0bddbb, answered

What color is #0bddbb?

#0bddbb is a balanced electric cyan, closest to Turquoise (ΔE2000 5.6). It sits at 170° on the hue wheel with 91% saturation and 46% lightness, which reads as cool.

What is the RGB value of #0bddbb?

rgb(11, 221, 187) — 11 red, 221 green and 187 blue out of 255, or 4.3% / 86.7% / 73.3% by channel.

What is #0bddbb in HSL and HSV?

hsl(170, 91%, 46%) and hsv(170, 95%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #0bddbb a light or a dark color?

It is a light color. Relative luminance is 0.5537 and perceived brightness is 71%, so black text on it reaches 12.07:1.

Should I use black or white text on #0bddbb?

Black. It scores 12.07:1 against #0bddbb, versus 1.74:1 for white — AAA at any size.

Is #0bddbb accessible on a white background?

#0bddbb on white scores 1.74:1, which fails WCAG AA at every size. Darken it to #078671 to reach 4.5:1, or #056454 for 7:1.

What is the complementary color of #0bddbb?

#DD0B2D sits directly opposite on the wheel. Softer options are the split-complements #DD0B96 and #DD520B, which give the same contrast with far less vibration.

What colors go well with #0bddbb?

For interface work: #F4FAF9 as the surface, #C0EDE5 for borders, #4B9B8E for secondary text, #E20661 as an accent and #067967 for hover and pressed states. For a palette, the analogous pair #0BDD52 and #0B96DD stays calm, while #DD0B2D is the loudest partner.

What is #0bddbb in CMYK for printing?

cmyk(95%, 0%, 15%, 13%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #0bddbb warm or cool?

Cool — it scores 83 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #0BDD6E; nudged cooler, #09B8DF.

Which Tailwind color is closest to #0bddbb?

The teal family — its 500 step is #14b8a6, ΔE2000 10 away. That is a visible difference, so define #0bddbb as a custom token rather than reaching for the built-in.

How do I use #0bddbb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#0bddbb] or text-[#0bddbb], 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 #0bddbb with 50% opacity?

rgba(11, 221, 187, 0.5), or #0bddbb80 in eight-digit hex. Over white that composites to #85EEDD; over black, #066F5E.

Is #0bddbb a web-safe color?

No. The nearest web-safe colour is #00CCCC, ΔE2000 11.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #0bddbb 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 #0bddbb?

The safest is same-hue elevation: linear-gradient(135deg, #31F5D5, #0bddbb 45%, #067967). For more colour, a short hue run to #0A55C0 keeps it rich without turning muddy.
