How to use #eef3f2

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • 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 #354B46
Safe as a 1px border on white
No — use #739C94

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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. 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.

#eef3f2, answered

What color is #eef3f2?

#eef3f2 is a pale soft cyan, closest to White Smoke (ΔE2000 2.7). It sits at 168° on the hue wheel with 17% saturation and 94% lightness, which reads as cool.

What is the RGB value of #eef3f2?

rgb(238, 243, 242) — 238 red, 243 green and 242 blue out of 255, or 93.3% / 95.3% / 94.9% by channel.

What is #eef3f2 in HSL and HSV?

hsl(168, 17%, 94%) and hsv(168, 2%, 95%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #eef3f2 a light or a dark color?

It is a light color. Relative luminance is 0.8869 and perceived brightness is 95%, so black text on it reaches 18.74:1.

Should I use black or white text on #eef3f2?

Black. It scores 18.74:1 against #eef3f2, versus 1.12:1 for white — AAA at any size.

Is #eef3f2 accessible on a white background?

#eef3f2 on white scores 1.12:1, which fails WCAG AA at every size. Darken it to #577B74 to reach 4.5:1, or #425E58 for 7:1.

What is the complementary color of #eef3f2?

#F3EEEF sits directly opposite on the wheel. Softer options are the split-complements #F3EEF1 and #F3EFEE, which give the same contrast with far less vibration.

What colors go well with #eef3f2?

For interface work: #F6F9F8 as the surface, #CFDDDA for borders, #5F867F for secondary text, #7F4D62 as an accent and #354B46 for hover and pressed states. For a palette, the analogous pair #EEF3EF and #EEF1F3 stays calm, while #F3EEEF is the loudest partner.

What is #eef3f2 in CMYK for printing?

cmyk(2%, 0%, 0%, 5%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #eef3f2 warm or cool?

Cool — it scores 66 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #EEF3F0; nudged cooler, #EEF2F3.

Which Tailwind color is closest to #eef3f2?

The cyan family — its 500 step is #06b6d4, ΔE2000 27.9 away. That is a visible difference, so define #eef3f2 as a custom token rather than reaching for the built-in.

How do I use #eef3f2 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#eef3f2] or text-[#eef3f2], 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 #eef3f2 with 50% opacity?

rgba(238, 243, 242, 0.5), or #eef3f280 in eight-digit hex. Over white that composites to #F7F9F9; over black, #777A79.

Is #eef3f2 a web-safe color?

No. The nearest web-safe colour is #FFFFFF, ΔE2000 3.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #eef3f2 mean?

As a cyan, it reads clean, technical, fresh. Cyan reads as water, air and infrastructure: cool, hygienic, engineered. At this moderate chroma the association is present but not shouted.

What gradient works with #eef3f2?

The safest is same-hue elevation: linear-gradient(135deg, #F3F7F6, #eef3f2 45%, #354B46). For more colour, a short hue run to #DCE1E6 keeps it rich without turning muddy.
