How to use #6eb2ee

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 #0D4372
Safe as a 1px border on white
No — use #3C97E8

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 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.

Transparency

What each alpha value actually composites to. The top row is #6eb2ee over white; the bottom row is the same alpha over a checkerboard, so you can see what survives on a photo or a video.

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.

#6eb2ee, answered

What color is #6eb2ee?

#6eb2ee is a light electric blue, closest to Light Sky Blue (ΔE2000 8). It sits at 208° on the hue wheel with 79% saturation and 68% lightness, which reads as cool.

What is the RGB value of #6eb2ee?

rgb(110, 178, 238) — 110 red, 178 green and 238 blue out of 255, or 43.1% / 69.8% / 93.3% by channel.

What is #6eb2ee in HSL and HSV?

hsl(208, 79%, 68%) and hsv(208, 54%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #6eb2ee a light or a dark color?

It is a mid-tone. Relative luminance is 0.4133 and perceived brightness is 66%, so black text on it reaches 9.27:1.

Should I use black or white text on #6eb2ee?

Black. It scores 9.27:1 against #6eb2ee, versus 2.27:1 for white — AAA at any size.

Is #6eb2ee accessible on a white background?

#6eb2ee on white scores 2.27:1, which fails WCAG AA at every size. Darken it to #1879CE to reach 4.5:1, or #125998 for 7:1.

What is the complementary color of #6eb2ee?

#EEAA6E sits directly opposite on the wheel. Softer options are the split-complements #EE6E72 and #EEEA6E, which give the same contrast with far less vibration.

What colors go well with #6eb2ee?

For interface work: #F4F8FA as the surface, #C0D8ED for borders, #4B759B for secondary text, #BA3612 as an accent and #0D4372 for hover and pressed states. For a palette, the analogous pair #6EEEEA and #6E72EE stays calm, while #EEAA6E is the loudest partner.

What is #6eb2ee in CMYK for printing?

cmyk(54%, 25%, 0%, 7%). 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 #6eb2ee warm or cool?

Cool — it scores 99 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #6E83EE; nudged cooler, #55A0ED.

Which Tailwind color is closest to #6eb2ee?

The sky family — its 500 step is #0ea5e9, ΔE2000 7.3 away. That is a visible difference, so define #6eb2ee as a custom token rather than reaching for the built-in.

How do I use #6eb2ee in Tailwind CSS?

Inline it as an arbitrary value with bg-[#6eb2ee] or text-[#6eb2ee], 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 #6eb2ee with 50% opacity?

rgba(110, 178, 238, 0.5), or #6eb2ee80 in eight-digit hex. Over white that composites to #B7D9F7; over black, #375977.

Is #6eb2ee a web-safe color?

No. The nearest web-safe colour is #6699FF, ΔE2000 8.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #6eb2ee mean?

As a blue, it reads trusted, calm, competent. 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 effect is amplified — it will dominate whatever sits beside it.

What gradient works with #6eb2ee?
