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 #1cec67

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 #0A7631
Safe as a 1px border on white
No — use #0EA946

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 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 #1cec67 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.

#1cec67, answered

What color is #1cec67?

#1cec67 is a balanced electric green, closest to Spring Green (ΔE2000 4.3). It sits at 142° on the hue wheel with 85% saturation and 52% lightness, which reads as cool.

What is the RGB value of #1cec67?

rgb(28, 236, 103) — 28 red, 236 green and 103 blue out of 255, or 11% / 92.5% / 40.4% by channel.

What is #1cec67 in HSL and HSV?

hsl(142, 85%, 52%) and hsv(142, 88%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #1cec67 a light or a dark color?

It is a light color. Relative luminance is 0.6122 and perceived brightness is 72%, so black text on it reaches 13.24:1.

Should I use black or white text on #1cec67?

Black. It scores 13.24:1 against #1cec67, versus 1.59:1 for white — AAA at any size.

Is #1cec67 accessible on a white background?

#1cec67 on white scores 1.59:1, which fails WCAG AA at every size. Darken it to #0B8838 to reach 4.5:1, or #09672A for 7:1.

What is the complementary color of #1cec67?

#EC1CA1 sits directly opposite on the wheel. Softer options are the split-complements #CF1CEC and #EC1C39, which give the same contrast with far less vibration.

What colors go well with #1cec67?

For interface work: #F4FAF6 as the surface, #C0EDD0 for borders, #4B9B68 for secondary text, #F117D9 as an accent and #0A7631 for hover and pressed states. For a palette, the analogous pair #39EC1C and #1CECCF stays calm, while #EC1CA1 is the loudest partner.

What is #1cec67 in CMYK for printing?

cmyk(88%, 0%, 56%, 8%). 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 #1cec67 warm or cool?

Cool — it scores 72 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #1DEC1C; nudged cooler, #1AEFB4.

Which Tailwind color is closest to #1cec67?

The green family — its 500 step is #22c55e, ΔE2000 9.5 away. That is a visible difference, so define #1cec67 as a custom token rather than reaching for the built-in.

How do I use #1cec67 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#1cec67] or text-[#1cec67], 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 #1cec67 with 50% opacity?

rgba(28, 236, 103, 0.5), or #1cec6780 in eight-digit hex. Over white that composites to #8EF6B3; over black, #0E7634.

Is #1cec67 a web-safe color?

No. The nearest web-safe colour is #33FF66, ΔE2000 4.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #1cec67 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 #1cec67?
