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 #78fdbf

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
  • Status meaning — pair it with an icon or label, never colour alone
  • 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 #027E44
Safe as a 1px border on white
No — use #03AB5D

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

safegrowingnaturalpermissive

Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed.

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

Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

Transparency

What each alpha value actually composites to. The top row is #78fdbf 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.

#78fdbf, answered

What color is #78fdbf?

#78fdbf is a light electric green, closest to Aqua Marine (ΔE2000 4.5). It sits at 152° on the hue wheel with 97% saturation and 73% lightness, which reads as cool.

What is the RGB value of #78fdbf?

rgb(120, 253, 191) — 120 red, 253 green and 191 blue out of 255, or 47.1% / 99.2% / 74.9% by channel.

What is #78fdbf in HSL and HSV?

hsl(152, 97%, 73%) and hsv(152, 53%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #78fdbf a light or a dark color?

It is a light color. Relative luminance is 0.7801 and perceived brightness is 84%, so black text on it reaches 16.60:1.

Should I use black or white text on #78fdbf?

Black. It scores 16.60:1 against #78fdbf, versus 1.26:1 for white — AAA at any size.

Is #78fdbf accessible on a white background?

#78fdbf on white scores 1.26:1, which fails WCAG AA at every size. Darken it to #02884A to reach 4.5:1, or #016537 for 7:1.

What is the complementary color of #78fdbf?

#FD78B6 sits directly opposite on the wheel. Softer options are the split-complements #FD78F9 and #FD7C78, which give the same contrast with far less vibration.

What colors go well with #78fdbf?

For interface work: #F4FAF8 as the surface, #C0EDD8 for borders, #4B9B75 for secondary text, #CC0092 as an accent and #027E44 for hover and pressed states. For a palette, the analogous pair #78FD7C and #78F9FD stays calm, while #FD78B6 is the loudest partner.

What is #78fdbf in CMYK for printing?

cmyk(53%, 0%, 25%, 1%). 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 #78fdbf warm or cool?

Cool — it scores 76 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #78FD8E; nudged cooler, #76FEF1.

Which Tailwind color is closest to #78fdbf?

The green family — its 500 step is #22c55e, ΔE2000 16.3 away. That is a visible difference, so define #78fdbf as a custom token rather than reaching for the built-in.

How do I use #78fdbf in Tailwind CSS?

Inline it as an arbitrary value with bg-[#78fdbf] or text-[#78fdbf], 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 #78fdbf with 50% opacity?

rgba(120, 253, 191, 0.5), or #78fdbf80 in eight-digit hex. Over white that composites to #BCFEDF; over black, #3C7F60.

Is #78fdbf a web-safe color?

No. The nearest web-safe colour is #66FFCC, ΔE2000 3.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #78fdbf mean?

As a green, it reads safe, growing, natural. Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #78fdbf?
