How to use #16640f

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Body text and links on white
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Text on black or near-black surfaces
  • Full-page backgrounds — tiring over long sessions
  • Black text placed on it
  • 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

Safe as a fill behind white type
Yes
Safe as a 1px border on white

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 low lightness adds weight and formality.

Worth knowing

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

What each alpha value actually composites to. The top row is #16640f 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.

#16640f, answered

What color is #16640f?

#16640f is a deep vivid green, closest to Dark Green (ΔE2000 1.5). It sits at 115° on the hue wheel with 74% saturation and 23% lightness, which reads as cool.

What is the RGB value of #16640f?

rgb(22, 100, 15) — 22 red, 100 green and 15 blue out of 255, or 8.6% / 39.2% / 5.9% by channel.

What is #16640f in HSL and HSV?

hsl(115, 74%, 23%) and hsv(115, 85%, 39%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #16640f a light or a dark color?

It is a dark color. Relative luminance is 0.0932 and perceived brightness is 30%, so white text on it reaches 7.33:1.

Should I use black or white text on #16640f?

White. It scores 7.33:1 against #16640f, versus 2.86:1 for black — AAA at any size.

Is #16640f accessible on a white background?

#16640f on white scores 7.33:1, which clears AAA at every size.

What is the complementary color of #16640f?

#5D0F64 sits directly opposite on the wheel. Softer options are the split-complements #320F64 and #640F40, which give the same contrast with far less vibration.

What colors go well with #16640f?

For interface work: #F5FAF4 as the surface, #C3EDC0 for borders, #519B4B for secondary text, #480D66 as an accent and #186F11 for hover and pressed states. For a palette, the analogous pair #40640F and #0F6432 stays calm, while #5D0F64 is the loudest partner.

What is #16640f in CMYK for printing?

cmyk(78%, 0%, 85%, 61%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #16640f warm or cool?

Cool — it scores 60 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #35640F; nudged cooler, #0E6527.

Which Tailwind color is closest to #16640f?

The neutral family — its 500 step is #737373, ΔE2000 27.3 away. That is a visible difference, so define #16640f as a custom token rather than reaching for the built-in.

How do I use #16640f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#16640f] or text-[#16640f], 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 #16640f with 50% opacity?

rgba(22, 100, 15, 0.5), or #16640f80 in eight-digit hex. Over white that composites to #8BB287; over black, #0B3208.

Is #16640f a web-safe color?
