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 #2cd290

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 #166948
Safe as a 1px border on white
No — use #23A873

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.

Transparency

What each alpha value actually composites to. The top row is #2cd290 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.

#2cd290, answered

What color is #2cd290?

#2cd290 is a balanced vivid green, closest to Medium Aqua Marine (ΔE2000 7.5). It sits at 156° on the hue wheel with 65% saturation and 50% lightness, which reads as cool.

What is the RGB value of #2cd290?

rgb(44, 210, 144) — 44 red, 210 green and 144 blue out of 255, or 17.3% / 82.4% / 56.5% by channel.

What is #2cd290 in HSL and HSV?

hsl(156, 65%, 50%) and hsv(156, 79%, 82%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #2cd290 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4864 and perceived brightness is 67%, so black text on it reaches 10.73:1.

Should I use black or white text on #2cd290?

Black. It scores 10.73:1 against #2cd290, versus 1.96:1 for white — AAA at any size.

Is #2cd290 accessible on a white background?

#2cd290 on white scores 1.96:1, which fails WCAG AA at every size. Darken it to #1C865C to reach 4.5:1, or #156445 for 7:1.

What is the complementary color of #2cd290?

#D22C6E sits directly opposite on the wheel. Softer options are the split-complements #D22CC1 and #D23D2C, which give the same contrast with far less vibration.

What colors go well with #2cd290?

For interface work: #F4FAF8 as the surface, #C0EDDB for borders, #4B9B7B for secondary text, #D72799 as an accent and #166948 for hover and pressed states. For a palette, the analogous pair #2CD23D and #2CC1D2 stays calm, while #D22C6E is the loudest partner.

What is #2cd290 in CMYK for printing?

cmyk(79%, 0%, 31%, 18%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #2cd290 warm or cool?

Cool — it scores 78 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #2CD253; nudged cooler, #29D5CF.

Which Tailwind color is closest to #2cd290?

The emerald family — its 500 step is #10b981, ΔE2000 6.6 away. That is a visible difference, so define #2cd290 as a custom token rather than reaching for the built-in.

How do I use #2cd290 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#2cd290] or text-[#2cd290], 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 #2cd290 with 50% opacity?

rgba(44, 210, 144, 0.5), or #2cd29080 in eight-digit hex. Over white that composites to #96E9C8; over black, #166948.

Is #2cd290 a web-safe color?
