How to use #f7f7fe

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
  • 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 #0E0E71
Safe as a 1px border on white
No — use #8A8AF0

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

trustedcalmcompetentcorporate

The default of institutions for a reason: blue is read as stable and safe across nearly every culture that has been surveyed.

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

It is also the most crowded hue on the web. Distinctiveness has to come from your other choices.

What each alpha value actually composites to. The top row is #f7f7fe 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.

#f7f7fe, answered

What color is #f7f7fe?

#f7f7fe is a pale electric blue — the CSS keyword Ghost White. It sits at 240° on the hue wheel with 78% saturation and 98% lightness, which reads as cool.

What is the RGB value of #f7f7fe?

rgb(247, 247, 254) — 247 red, 247 green and 254 blue out of 255, or 96.9% / 96.9% / 99.6% by channel.

What is #f7f7fe in HSL and HSV?

hsl(240, 78%, 98%) and hsv(240, 3%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #f7f7fe a light or a dark color?

It is a light color. Relative luminance is 0.9345 and perceived brightness is 97%, so black text on it reaches 19.69:1.

Should I use black or white text on #f7f7fe?

Black. It scores 19.69:1 against #f7f7fe, versus 1.07:1 for white — AAA at any size.

Is #f7f7fe accessible on a white background?

#f7f7fe on white scores 1.07:1, which fails WCAG AA at every size. Darken it to #6161EB to reach 4.5:1, or #3838E6 for 7:1.

What is the complementary color of #f7f7fe?

#FEFEF7 sits directly opposite on the wheel. Softer options are the split-complements #FEFAF7 and #FAFEF7, which give the same contrast with far less vibration.

What colors go well with #f7f7fe?

For interface work: #F4F4FA as the surface, #C0C0ED for borders, #4B4B9B for secondary text, #B58817 as an accent and #0E0E71 for hover and pressed states. For a palette, the analogous pair #F7FAFE and #FAF7FE stays calm, while #FEFEF7 is the loudest partner.

What is #f7f7fe in CMYK for printing?

cmyk(3%, 3%, 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 #f7f7fe 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 #F6F1FD; nudged cooler, #F1F6FD.

Which Tailwind color is closest to #f7f7fe?

The cyan family — its 500 step is #06b6d4, ΔE2000 32.3 away. That is a visible difference, so define #f7f7fe as a custom token rather than reaching for the built-in.

How do I use #f7f7fe in Tailwind CSS?

Inline it as an arbitrary value with bg-[#f7f7fe] or text-[#f7f7fe], 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 #f7f7fe with 50% opacity?

rgba(247, 247, 254, 0.5), or #f7f7fe80 in eight-digit hex. Over white that composites to #FBFBFF; over black, #7C7C7F.

Is #f7f7fe a web-safe color?

No. The nearest web-safe colour is #FFFFFF, ΔE2000 3.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #f7f7fe mean?
