How to use #7eb3d9

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 #1D4562
Safe as a 1px border on white
No — use #5399CC

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The lightness keeps it airy and approachable.

Worth knowing

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

#7eb3d9, answered

What color is #7eb3d9?

#7eb3d9 is a light vivid blue, closest to Light Sky Blue (ΔE2000 7.2). It sits at 205° on the hue wheel with 55% saturation and 67% lightness, which reads as cool.

What is the RGB value of #7eb3d9?

rgb(126, 179, 217) — 126 red, 179 green and 217 blue out of 255, or 49.4% / 70.2% / 85.1% by channel.

What is #7eb3d9 in HSL and HSV?

hsl(205, 55%, 67%) and hsv(205, 42%, 85%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #7eb3d9 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4169 and perceived brightness is 67%, so black text on it reaches 9.34:1.

Should I use black or white text on #7eb3d9?

Black. It scores 9.34:1 against #7eb3d9, versus 2.25:1 for white — AAA at any size.

Is #7eb3d9 accessible on a white background?

#7eb3d9 on white scores 2.25:1, which fails WCAG AA at every size. Darken it to #337BAF to reach 4.5:1, or #275C83 for 7:1.

What is the complementary color of #7eb3d9?

#D9A47E sits directly opposite on the wheel. Softer options are the split-complements #D97E86 and #D9D27E, which give the same contrast with far less vibration.

What colors go well with #7eb3d9?

For interface work: #F4F8FA as the surface, #C0DAEC for borders, #4B799B for secondary text, #A13E2B as an accent and #1D4562 for hover and pressed states. For a palette, the analogous pair #7ED9D2 and #7E86D9 stays calm, while #D9A47E is the loudest partner.

What is #7eb3d9 in CMYK for printing?

cmyk(42%, 18%, 0%, 15%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #7eb3d9 warm or cool?

Cool — it scores 98 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #7ED4D9; nudged cooler, #69A0D5.

Which Tailwind color is closest to #7eb3d9?

The sky family — its 500 step is #0ea5e9, ΔE2000 8.8 away. That is a visible difference, so define #7eb3d9 as a custom token rather than reaching for the built-in.

How do I use #7eb3d9 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#7eb3d9] or text-[#7eb3d9], 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 #7eb3d9 with 50% opacity?

rgba(126, 179, 217, 0.5), or #7eb3d980 in eight-digit hex. Over white that composites to #BFD9EC; over black, #3F5A6D.

Is #7eb3d9 a web-safe color?

No. The nearest web-safe colour is #66CCCC, ΔE2000 17.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #7eb3d9 mean?
