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 #2cd7fe

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 #01687F
Safe as a 1px border on white
No — use #019FC3

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 #2cd7fe 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.

#2cd7fe, answered

What color is #2cd7fe?

#2cd7fe is a balanced electric cyan, closest to Sky Blue (ΔE2000 7). It sits at 191° on the hue wheel with 99% saturation and 58% lightness, which reads as cool.

What is the RGB value of #2cd7fe?

rgb(44, 215, 254) — 44 red, 215 green and 254 blue out of 255, or 17.3% / 84.3% / 99.6% by channel.

What is #2cd7fe in HSL and HSV?

hsl(191, 99%, 58%) and hsv(191, 83%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #2cd7fe a light or a dark color?

It is a light color. Relative luminance is 0.5629 and perceived brightness is 73%, so black text on it reaches 12.26:1.

Should I use black or white text on #2cd7fe?

Black. It scores 12.26:1 against #2cd7fe, versus 1.71:1 for white — AAA at any size.

Is #2cd7fe accessible on a white background?

#2cd7fe on white scores 1.71:1, which fails WCAG AA at every size. Darken it to #017E9A to reach 4.5:1, or #016177 for 7:1.

What is the complementary color of #2cd7fe?

#FE532C sits directly opposite on the wheel. Softer options are the split-complements #FE2C6E and #FEBC2C, which give the same contrast with far less vibration.

What colors go well with #2cd7fe?

For interface work: #F4F9FA as the surface, #C0E4ED for borders, #4B8C9B for secondary text, #FF2B39 as an accent and #01687F for hover and pressed states. For a palette, the analogous pair #2CFEBC and #2C6EFE stays calm, while #FE532C is the loudest partner.

What is #2cd7fe in CMYK for printing?

cmyk(83%, 15%, 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 #2cd7fe warm or cool?

Cool — it scores 92 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #2CFED8; nudged cooler, #2BB5FF.

Which Tailwind color is closest to #2cd7fe?

The cyan family — its 500 step is #06b6d4, ΔE2000 8.8 away. That is a visible difference, so define #2cd7fe as a custom token rather than reaching for the built-in.

How do I use #2cd7fe in Tailwind CSS?

Inline it as an arbitrary value with bg-[#2cd7fe] or text-[#2cd7fe], 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 #2cd7fe with 50% opacity?

rgba(44, 215, 254, 0.5), or #2cd7fe80 in eight-digit hex. Over white that composites to #96EBFF; over black, #166C7F.

Is #2cd7fe a web-safe color?

No. The nearest web-safe colour is #33CCFF, ΔE2000 4.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #2cd7fe 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 #2cd7fe?

The safest is same-hue elevation: linear-gradient(135deg, #69E3FE, #2cd7fe 45%, #01687F). For more colour, a short hue run to #0D1DFE keeps it rich without turning muddy.
