How to use #649913

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

Works well for
  • Headings from 24px up on white
  • Text and icons on dark surfaces
  • 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
  • Small text on white — under 4.5:1
  • 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
24px / 18.66px bold
Safe as a fill behind white type
No — use #4A710E
Safe as a 1px border on white
Yes

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 #649913 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.

#649913, answered

What color is #649913?

#649913 is a dark electric green, closest to Olive Drab (ΔE2000 4.3). It sits at 84° on the hue wheel with 78% saturation and 34% lightness, which reads as neutral.

What is the RGB value of #649913?

rgb(100, 153, 19) — 100 red, 153 green and 19 blue out of 255, or 39.2% / 60% / 7.5% by channel.

What is #649913 in HSL and HSV?

hsl(84, 78%, 34%) and hsv(84, 88%, 60%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #649913 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2554 and perceived brightness is 51%, so black text on it reaches 6.11:1.

Should I use black or white text on #649913?

Black. It scores 6.11:1 against #649913, versus 3.44:1 for white — AA at any size.

Is #649913 accessible on a white background?

#649913 on white scores 3.44:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #558210 to reach 4.5:1, or #40620C for 7:1.

What is the complementary color of #649913?

#481399 sits directly opposite on the wheel. Softer options are the split-complements #132199 and #8B1399, which give the same contrast with far less vibration.

What colors go well with #649913?

For interface work: #F8FAF4 as the surface, #DBEDC0 for borders, #7B9B4B for secondary text, #24109C as an accent and #4A710E for hover and pressed states. For a palette, the analogous pair #998B13 and #219913 stays calm, while #481399 is the loudest partner.

What is #649913 in CMYK for printing?

cmyk(35%, 0%, 88%, 40%). 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 #649913 warm or cool?

Neutral — it scores 45 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #959913; nudged cooler, #329B11.

Which Tailwind color is closest to #649913?

The lime family — its 500 step is #84cc16, ΔE2000 14.6 away. That is a visible difference, so define #649913 as a custom token rather than reaching for the built-in.

How do I use #649913 in Tailwind CSS?
