Colour vision deficiency

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 #adcd63

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 #4D611F
Safe as a 1px border on white
No — use #7D9D32

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 #adcd63 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.

#adcd63, answered

What color is #adcd63?

#adcd63 is a balanced vivid green, closest to Yellow Green (ΔE2000 5.4). It sits at 78° on the hue wheel with 52% saturation and 60% lightness, which reads as warm.

What is the RGB value of #adcd63?

rgb(173, 205, 99) — 173 red, 205 green and 99 blue out of 255, or 67.8% / 80.4% / 38.8% by channel.

What is #adcd63 in HSL and HSV?

hsl(78, 52%, 60%) and hsv(78, 52%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #adcd63 a light or a dark color?

It is a light color. Relative luminance is 0.5345 and perceived brightness is 73%, so black text on it reaches 11.69:1.

Should I use black or white text on #adcd63?

Black. It scores 11.69:1 against #adcd63, versus 1.80:1 for white — AAA at any size.

Is #adcd63 accessible on a white background?

#adcd63 on white scores 1.80:1, which fails WCAG AA at every size. Darken it to #647E28 to reach 4.5:1, or #4C5F1E for 7:1.

What is the complementary color of #adcd63?

#8363CD sits directly opposite on the wheel. Softer options are the split-complements #6378CD and #B863CD, which give the same contrast with far less vibration.

What colors go well with #adcd63?

For interface work: #F9FAF4 as the surface, #DFEBC1 for borders, #839B4B for secondary text, #655FD1 as an accent and #4D611F for hover and pressed states. For a palette, the analogous pair #CDB863 and #78CD63 stays calm, while #8363CD is the loudest partner.

What is #adcd63 in CMYK for printing?

cmyk(16%, 0%, 52%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #adcd63 warm or cool?

Warm — it scores 40 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CDC663; nudged cooler, #85CF61.

Which Tailwind color is closest to #adcd63?

The lime family — its 500 step is #84cc16, ΔE2000 7.8 away. That is a visible difference, so define #adcd63 as a custom token rather than reaching for the built-in.

How do I use #adcd63 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#adcd63] or text-[#adcd63], 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 #adcd63 with 50% opacity?

rgba(173, 205, 99, 0.5), or #adcd6380 in eight-digit hex. Over white that composites to #D6E6B1; over black, #576732.

Is #adcd63 a web-safe color?

No. The nearest web-safe colour is #99CC66, ΔE2000 4 away. The palette only matters for legacy displays and some email clients now.

What does the color #adcd63 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 #adcd63?

The safest is same-hue elevation: linear-gradient(135deg, #C5DC91, #adcd63 45%, #4D611F). For more colour, a short hue run to #4CC652 keeps it rich without turning muddy.
