How to use #7eb3c9

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

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • 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 #264B5A
Safe as a 1px border on white
No — use #569CB8

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 mid lightness keeps it versatile in both themes.

Worth knowing

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

#7eb3c9, answered

What color is #7eb3c9?

#7eb3c9 is a balanced soft cyan, closest to Sky Blue (ΔE2000 7.2). It sits at 198° on the hue wheel with 41% saturation and 64% lightness, which reads as cool.

What is the RGB value of #7eb3c9?

rgb(126, 179, 201) — 126 red, 179 green and 201 blue out of 255, or 49.4% / 70.2% / 78.8% by channel.

What is #7eb3c9 in HSL and HSV?

hsl(198, 41%, 64%) and hsv(198, 37%, 79%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #7eb3c9 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4089 and perceived brightness is 66%, so black text on it reaches 9.18:1.

Should I use black or white text on #7eb3c9?

Black. It scores 9.18:1 against #7eb3c9, versus 2.29:1 for white — AAA at any size.

Is #7eb3c9 accessible on a white background?

#7eb3c9 on white scores 2.29:1, which fails WCAG AA at every size. Darken it to #3F7E97 to reach 4.5:1, or #2F5D70 for 7:1.

What is the complementary color of #7eb3c9?

#C9947E sits directly opposite on the wheel. Softer options are the split-complements #C97E8D and #C9B97E, which give the same contrast with far less vibration.

What colors go well with #7eb3c9?

For interface work: #F4F9FA as the surface, #C5DDE7 for borders, #4B839B for secondary text, #943C38 as an accent and #264B5A for hover and pressed states. For a palette, the analogous pair #7EC9B9 and #7E8DC9 stays calm, while #C9947E is the loudest partner.

What is #7eb3c9 in CMYK for printing?

cmyk(37%, 11%, 0%, 21%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #7eb3c9 warm or cool?

Cool — it scores 95 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #7EC9C3; nudged cooler, #7CA6CB.

Which Tailwind color is closest to #7eb3c9?

The cyan family — its 500 step is #06b6d4, ΔE2000 8.7 away. That is a visible difference, so define #7eb3c9 as a custom token rather than reaching for the built-in.

How do I use #7eb3c9 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#7eb3c9] or text-[#7eb3c9], 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 #7eb3c9 with 50% opacity?

rgba(126, 179, 201, 0.5), or #7eb3c980 in eight-digit hex. Over white that composites to #BFD9E4; over black, #3F5A65.

Is #7eb3c9 a web-safe color?

No. The nearest web-safe colour is #66CCCC, ΔE2000 13.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #7eb3c9 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.
