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.

Color scale — 50 to 950

How to use #25cf75

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
  • 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 #136C3D
Safe as a 1px border on white
No — use #1EA85F

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The mid lightness keeps it versatile in both themes.

Worth knowing

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

#25cf75, answered

What color is #25cf75?

#25cf75 is a balanced vivid green, closest to Medium Sea Green (ΔE2000 7.8). It sits at 148° on the hue wheel with 70% saturation and 48% lightness, which reads as cool.

What is the RGB value of #25cf75?

rgb(37, 207, 117) — 37 red, 207 green and 117 blue out of 255, or 14.5% / 81.2% / 45.9% by channel.

What is #25cf75 in HSL and HSV?

hsl(148, 70%, 48%) and hsv(148, 82%, 81%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #25cf75 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4630 and perceived brightness is 65%, so black text on it reaches 10.26:1.

Should I use black or white text on #25cf75?

Black. It scores 10.26:1 against #25cf75, versus 2.05:1 for white — AAA at any size.

Is #25cf75 accessible on a white background?

#25cf75 on white scores 2.05:1, which fails WCAG AA at every size. Darken it to #18854B to reach 4.5:1, or #126338 for 7:1.

What is the complementary color of #25cf75?

#CF257F sits directly opposite on the wheel. Softer options are the split-complements #CA25CF and #CF252A, which give the same contrast with far less vibration.

What colors go well with #25cf75?

For interface work: #F4FAF7 as the surface, #C0EDD5 for borders, #4B9B70 for secondary text, #D420AC as an accent and #136C3D for hover and pressed states. For a palette, the analogous pair #2ACF25 and #25CFCA stays calm, while #CF257F is the loudest partner.

What is #25cf75 in CMYK for printing?

cmyk(82%, 0%, 44%, 19%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #25cf75 warm or cool?

Cool — it scores 74 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #25CF36; nudged cooler, #22D1B5.

Which Tailwind color is closest to #25cf75?

The green family — its 500 step is #22c55e, ΔE2000 3.6 away. That is a visible difference, so define #25cf75 as a custom token rather than reaching for the built-in.

How do I use #25cf75 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#25cf75] or text-[#25cf75], 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 #25cf75 with 50% opacity?

rgba(37, 207, 117, 0.5), or #25cf7580 in eight-digit hex. Over white that composites to #92E7BA; over black, #13683B.

Is #25cf75 a web-safe color?

No. The nearest web-safe colour is #33CC66, ΔE2000 2.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #25cf75 mean?
