How to use #f5f7fe

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 #0C2374
Safe as a 1px border on white
No — use #738FF1

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.

#f5f7fe, answered

What color is #f5f7fe?

#f5f7fe is a pale electric blue, closest to Ghost White (ΔE2000 1). It sits at 227° on the hue wheel with 82% saturation and 98% lightness, which reads as cool.

What is the RGB value of #f5f7fe?

rgb(245, 247, 254) — 245 red, 247 green and 254 blue out of 255, or 96.1% / 96.9% / 99.6% by channel.

What is #f5f7fe in HSL and HSV?

hsl(227, 82%, 98%) and hsv(227, 4%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #f5f7fe a light or a dark color?

It is a light color. Relative luminance is 0.9309 and perceived brightness is 97%, so black text on it reaches 19.62:1.

Should I use black or white text on #f5f7fe?

Black. It scores 19.62:1 against #f5f7fe, versus 1.07:1 for white — AAA at any size.

Is #f5f7fe accessible on a white background?

#f5f7fe on white scores 1.07:1, which fails WCAG AA at every size. Darken it to #456AEC to reach 4.5:1, or #1744E2 for 7:1.

What is the complementary color of #f5f7fe?

#FEFCF5 sits directly opposite on the wheel. Softer options are the split-complements #FEF7F5 and #FBFEF5, which give the same contrast with far less vibration.

What colors go well with #f5f7fe?

For interface work: #F4F6FA as the surface, #C0CAED for borders, #4B5C9B for secondary text, #B96F13 as an accent and #0C2374 for hover and pressed states. For a palette, the analogous pair #F5FBFE and #F7F5FE stays calm, while #FEFCF5 is the loudest partner.

What is #f5f7fe in CMYK for printing?

cmyk(4%, 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 #f5f7fe warm or cool?

Cool — it scores 91 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #F3F1FE; nudged cooler, #F1F7FE.

Which Tailwind color is closest to #f5f7fe?

The cyan family — its 500 step is #06b6d4, ΔE2000 30.3 away. That is a visible difference, so define #f5f7fe as a custom token rather than reaching for the built-in.

How do I use #f5f7fe in Tailwind CSS?

Inline it as an arbitrary value with bg-[#f5f7fe] or text-[#f5f7fe], 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 #f5f7fe with 50% opacity?

rgba(245, 247, 254, 0.5), or #f5f7fe80 in eight-digit hex. Over white that composites to #FAFBFF; over black, #7B7C7F.

Is #f5f7fe 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 #f5f7fe mean?
