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 #1fcc56

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 #116F2F
Safe as a 1px border on white
No — use #1AA947

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 #1fcc56 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.

#1fcc56, answered

What color is #1fcc56?

#1fcc56 is a balanced vivid green, closest to Lime Green (ΔE2000 4.4). It sits at 139° on the hue wheel with 74% saturation and 46% lightness, which reads as cool.

What is the RGB value of #1fcc56?

rgb(31, 204, 86) — 31 red, 204 green and 86 blue out of 255, or 12.2% / 80% / 33.7% by channel.

What is #1fcc56 in HSL and HSV?

hsl(139, 74%, 46%) and hsv(139, 85%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #1fcc56 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4415 and perceived brightness is 63%, so black text on it reaches 9.83:1.

Should I use black or white text on #1fcc56?

Black. It scores 9.83:1 against #1fcc56, versus 2.14:1 for white — AAA at any size.

Is #1fcc56 accessible on a white background?

#1fcc56 on white scores 2.14:1, which fails WCAG AA at every size. Darken it to #148538 to reach 4.5:1, or #10662B for 7:1.

What is the complementary color of #1fcc56?

#CC1F95 sits directly opposite on the wheel. Softer options are the split-complements #AD1FCC and #CC1F3E, which give the same contrast with far less vibration.

What colors go well with #1fcc56?

For interface work: #F4FAF6 as the surface, #C0EDCE for borders, #4B9B64 for secondary text, #D11AC4 as an accent and #116F2F for hover and pressed states. For a palette, the analogous pair #3ECC1F and #1FCCAD stays calm, while #CC1F95 is the loudest partner.

What is #1fcc56 in CMYK for printing?

cmyk(85%, 0%, 58%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #1fcc56 warm or cool?

Cool — it scores 70 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #27CC1F; nudged cooler, #1DCE96.

Which Tailwind color is closest to #1fcc56?

The green family — its 500 step is #22c55e, ΔE2000 2.5 away. That is close enough to swap in without anyone noticing.

How do I use #1fcc56 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#1fcc56] or text-[#1fcc56], 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 #1fcc56 with 50% opacity?

rgba(31, 204, 86, 0.5), or #1fcc5680 in eight-digit hex. Over white that composites to #8FE6AB; over black, #10662B.

Is #1fcc56 a web-safe color?

No. The nearest web-safe colour is #33CC66, ΔE2000 2.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #1fcc56 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 #1fcc56?

The safest is same-hue elevation: linear-gradient(135deg, #46E378, #1fcc56 45%, #116F2F). For more colour, a short hue run to #1BA7B2 keeps it rich without turning muddy.
