How to use #064521

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
Any size
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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. 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 #064521 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.

#064521, answered

What color is #064521?

#064521 is a deep electric green, closest to Dark Green (ΔE2000 13.6). It sits at 146° on the hue wheel with 84% saturation and 15% lightness, which reads as cool.

What is the RGB value of #064521?

rgb(6, 69, 33) — 6 red, 69 green and 33 blue out of 255, or 2.4% / 27.1% / 12.9% by channel.

What is #064521 in HSL and HSV?

hsl(146, 84%, 15%) and hsv(146, 91%, 27%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #064521 a light or a dark color?

It is a dark color. Relative luminance is 0.0440 and perceived brightness is 21%, so white text on it reaches 11.16:1.

Should I use black or white text on #064521?

White. It scores 11.16:1 against #064521, versus 1.88:1 for black — AAA at any size.

Is #064521 accessible on a white background?

#064521 on white scores 11.16:1, which clears AAA at every size.

What is the complementary color of #064521?

#45062A sits directly opposite on the wheel. Softer options are the split-complements #400645 and #45060B, which give the same contrast with far less vibration.

What colors go well with #064521?

For interface work: #F4FAF7 as the surface, #C0EDD3 for borders, #4B9B6D for secondary text, #46043B as an accent and #0A7538 for hover and pressed states. For a palette, the analogous pair #0B4506 and #064540 stays calm, while #45062A is the loudest partner.

What is #064521 in CMYK for printing?

cmyk(91%, 0%, 52%, 73%). 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 #064521 warm or cool?

Cool — it scores 73 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #06450A; nudged cooler, #054639.

Which Tailwind color is closest to #064521?

The neutral family — its 500 step is #737373, ΔE2000 29.4 away. That is a visible difference, so define #064521 as a custom token rather than reaching for the built-in.

How do I use #064521 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#064521] or text-[#064521], 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 #064521 with 50% opacity?

rgba(6, 69, 33, 0.5), or #06452180 in eight-digit hex. Over white that composites to #83A290; over black, #032311.

Is #064521 a web-safe color?
