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 #f0fefe

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 #087878
Safe as a 1px border on white
No — use #0BA2A2

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 high lightness makes it recede — a surface colour rather than a statement.

Worth knowing

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

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.

#f0fefe, answered

What color is #f0fefe?

#f0fefe is a pale electric cyan — the CSS keyword Azure. It sits at 180° on the hue wheel with 88% saturation and 97% lightness, which reads as cool.

What is the RGB value of #f0fefe?

rgb(240, 254, 254) — 240 red, 254 green and 254 blue out of 255, or 94.1% / 99.6% / 99.6% by channel.

What is #f0fefe in HSL and HSV?

hsl(180, 88%, 97%) and hsv(180, 6%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #f0fefe a light or a dark color?

It is a light color. Relative luminance is 0.9656 and perceived brightness is 98%, so black text on it reaches 20.31:1.

Should I use black or white text on #f0fefe?

Black. It scores 20.31:1 against #f0fefe, versus 1.03:1 for white — AAA at any size.

Is #f0fefe accessible on a white background?

#f0fefe on white scores 1.03:1, which fails WCAG AA at every size. Darken it to #098181 to reach 4.5:1, or #065F5F for 7:1.

What is the complementary color of #f0fefe?

#FEF0F0 sits directly opposite on the wheel. Softer options are the split-complements #FEF0F7 and #FEF7F0, which give the same contrast with far less vibration.

What colors go well with #f0fefe?

For interface work: #F4FAFA as the surface, #C0EDED for borders, #4B9B9B for secondary text, #BF0D33 as an accent and #087878 for hover and pressed states. For a palette, the analogous pair #F0FEF7 and #F0F7FE stays calm, while #FEF0F0 is the loudest partner.

What is #f0fefe in CMYK for printing?

cmyk(6%, 0%, 0%, 0%). 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 #f0fefe warm or cool?

Cool — it scores 88 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #F0FEF9; nudged cooler, #F0F9FE.

Which Tailwind color is closest to #f0fefe?

The cyan family — its 500 step is #06b6d4, ΔE2000 27.3 away. That is a visible difference, so define #f0fefe as a custom token rather than reaching for the built-in.

How do I use #f0fefe in Tailwind CSS?

Inline it as an arbitrary value with bg-[#f0fefe] or text-[#f0fefe], 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 #f0fefe with 50% opacity?

rgba(240, 254, 254, 0.5), or #f0fefe80 in eight-digit hex. Over white that composites to #F8FFFF; over black, #787F7F.

Is #f0fefe a web-safe color?

No. The nearest web-safe colour is #FFFFFF, ΔE2000 6.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #f0fefe 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 #f0fefe?

The safest is same-hue elevation: linear-gradient(135deg, #ECFEFE, #f0fefe 45%, #087878). For more colour, a short hue run to #D3DEFC keeps it rich without turning muddy.
