How to use #7eb7bb

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 #2C5154
Safe as a 1px border on white
No — use #57A0A5

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.

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.

#7eb7bb, answered

What color is #7eb7bb?

#7eb7bb is a balanced soft cyan, closest to Cadet Blue (ΔE2000 8). It sits at 184° on the hue wheel with 31% saturation and 61% lightness, which reads as cool.

What is the RGB value of #7eb7bb?

rgb(126, 183, 187) — 126 red, 183 green and 187 blue out of 255, or 49.4% / 71.8% / 73.3% by channel.

What is #7eb7bb in HSL and HSV?

hsl(184, 31%, 61%) and hsv(184, 33%, 73%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #7eb7bb a light or a dark color?

It is a mid-tone. Relative luminance is 0.4189 and perceived brightness is 66%, so black text on it reaches 9.38:1.

Should I use black or white text on #7eb7bb?

Black. It scores 9.38:1 against #7eb7bb, versus 2.24:1 for white — AAA at any size.

Is #7eb7bb accessible on a white background?

#7eb7bb on white scores 2.24:1, which fails WCAG AA at every size. Darken it to #447C80 to reach 4.5:1, or #345F62 for 7:1.

What is the complementary color of #7eb7bb?

#BB827E sits directly opposite on the wheel. Softer options are the split-complements #BB7E99 and #BBA17E, which give the same contrast with far less vibration.

What colors go well with #7eb7bb?

For interface work: #F5F9FA as the surface, #CAE1E3 for borders, #4F9296 for secondary text, #BF7A87 as an accent and #2C5154 for hover and pressed states. For a palette, the analogous pair #7EBBA1 and #7E99BB stays calm, while #BB827E is the loudest partner.

What is #7eb7bb in CMYK for printing?

cmyk(33%, 2%, 0%, 27%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #7eb7bb warm or cool?

Cool — it scores 85 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #7EBBA9; nudged cooler, #7CA2BD.

Which Tailwind color is closest to #7eb7bb?

The cyan family — its 500 step is #06b6d4, ΔE2000 10.1 away. That is a visible difference, so define #7eb7bb as a custom token rather than reaching for the built-in.

How do I use #7eb7bb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#7eb7bb] or text-[#7eb7bb], 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 #7eb7bb with 50% opacity?

rgba(126, 183, 187, 0.5), or #7eb7bb80 in eight-digit hex. Over white that composites to #BFDBDD; over black, #3F5C5E.

Is #7eb7bb a web-safe color?

No. The nearest web-safe colour is #66CCCC, ΔE2000 7.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #7eb7bb 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 #7eb7bb?

The safest is same-hue elevation: linear-gradient(135deg, #A6CDD0, #7eb7bb 45%, #2C5154). For more colour, a short hue run to #6A77B1 keeps it rich without turning muddy.
