Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.

How to use #36ebfe

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
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #01737F
Safe as a 1px border on white
No — use #01A3B4

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. The mid lightness keeps it versatile in both themes.

Worth knowing

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

What each alpha value actually composites to. The top row is #36ebfe 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.

#36ebfe, answered

What color is #36ebfe?

#36ebfe is a balanced electric cyan, closest to Cyan (ΔE2000 7.7). It sits at 186° on the hue wheel with 99% saturation and 60% lightness, which reads as cool.

What is the RGB value of #36ebfe?

rgb(54, 235, 254) — 54 red, 235 green and 254 blue out of 255, or 21.2% / 92.2% / 99.6% by channel.

What is #36ebfe in HSL and HSV?

hsl(186, 99%, 60%) and hsv(186, 79%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #36ebfe a light or a dark color?

It is a light color. Relative luminance is 0.6736 and perceived brightness is 79%, so black text on it reaches 14.47:1.

Should I use black or white text on #36ebfe?

Black. It scores 14.47:1 against #36ebfe, versus 1.45:1 for white — AAA at any size.

Is #36ebfe accessible on a white background?

#36ebfe on white scores 1.45:1, which fails WCAG AA at every size. Darken it to #018290 to reach 4.5:1, or #01626D for 7:1.

What is the complementary color of #36ebfe?

#FE4936 sits directly opposite on the wheel. Softer options are the split-complements #FE3687 and #FEAD36, which give the same contrast with far less vibration.

What colors go well with #36ebfe?

For interface work: #F4FAFA as the surface, #C0E8ED for borders, #4B939B for secondary text, #FF3554 as an accent and #01737F for hover and pressed states. For a palette, the analogous pair #36FEAD and #3687FE stays calm, while #FE4936 is the loudest partner.

What is #36ebfe in CMYK for printing?

cmyk(79%, 8%, 0%, 0%). 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 #36ebfe warm or cool?

Cool — it scores 90 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #36FEC8; nudged cooler, #35C1FF.

Which Tailwind color is closest to #36ebfe?

The cyan family — its 500 step is #06b6d4, ΔE2000 13.6 away. That is a visible difference, so define #36ebfe as a custom token rather than reaching for the built-in.

How do I use #36ebfe in Tailwind CSS?

Inline it as an arbitrary value with bg-[#36ebfe] or text-[#36ebfe], 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 #36ebfe with 50% opacity?

rgba(54, 235, 254, 0.5), or #36ebfe80 in eight-digit hex. Over white that composites to #9BF5FF; over black, #1B767F.

Is #36ebfe a web-safe color?

No. The nearest web-safe colour is #33FFFF, ΔE2000 7.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #36ebfe mean?

As a cyan, it reads clean, technical, fresh. Cyan reads as water, air and infrastructure: cool, hygienic, engineered. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #36ebfe?

The safest is same-hue elevation: linear-gradient(135deg, #73F1FE, #36ebfe 45%, #01737F). For more colour, a short hue run to #183BFE keeps it rich without turning muddy.
