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 #174721

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

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.

Transparency

What each alpha value actually composites to. The top row is #174721 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.

#174721, answered

What color is #174721?

#174721 is a deep vivid green, closest to Dark Green (ΔE2000 12.7). It sits at 133° on the hue wheel with 51% saturation and 18% lightness, which reads as cool.

What is the RGB value of #174721?

What is #174721 in HSL and HSV?

hsl(133, 51%, 18%) and hsv(133, 68%, 28%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

For interface work: #F4FAF6 as the surface, #C1EBCA for borders, #4B9B5B for secondary text, #471549 as an accent and #1F602D for hover and pressed states. For a palette, the analogous pair #254717 and #174739 stays calm, while #47173D is the loudest partner.

cmyk(68%, 0%, 54%, 72%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Which Tailwind color is closest to #174721?

The neutral family — its 500 step is #737373, ΔE2000 28.4 away. That is a visible difference, so define #174721 as a custom token rather than reaching for the built-in.

How do I use #174721 in Tailwind CSS?

What is #174721 with 50% opacity?
