The short answer: RGB 0, 100, 0

The most widely recognized dark green RGB value is 0, 100, 0, which is written as #006400 in hexadecimal. This is the color defined as "darkgreen" in the CSS named-color list used by web browsers, so it is a stable, documented reference point rather than an arbitrary pick.

There is no single universal "dark green," though. The phrase describes a range of deep greens, and many brands define their own. The CSS value is a useful default when no brand specification exists, but if you are matching an existing logo, the correct code is whatever that brand's guidelines specify. No brand-specific values were available for this article, so none are given here.

How the same color is written in different notations

  • RGB: 0, 100, 0 (red, green and blue channels, each on a 0–255 scale)
  • Hex: #006400 (the same three values in base 16; 100 in decimal is 64 in hex)
  • CSS name: darkgreen
  • CSS functional notation: rgb(0, 100, 0)

All four lines describe the same screen color. Vector editors generally accept RGB or hex input directly, so you can enter either value into a fill or stroke field.

Applying dark green in vector logo artwork

In a vector logo, the color is stored as a property of each shape's fill or stroke, so it can be changed later without loss of quality. In an SVG file, for example, a dark green shape can be declared like this:

<path d="..." fill="#006400" />

For a gradient, each color stop holds its own value. The example below runs from CSS darkgreen to CSS green (rgb(0, 128, 0), hex #008000), keeping the blend within one hue family. The stop colors are illustrative, not a recommendation for any particular brand.

<linearGradient id="darkGreenFade" x1="0" y1="0" x2="1" y2="0">
  <stop offset="0" stop-color="#006400" />
  <stop offset="1" stop-color="#008000" />
</linearGradient>
<path d="..." fill="url(#darkGreenFade)" />

Sampling a dark green from an existing logo file

If you are trying to read the dark green out of a logo you already have, the type of artwork matters. In true vector artwork, the fill value stored on the shape is the defined color. If the file contains an embedded raster image, or you are looking at a raster preview such as a PNG or JPG thumbnail, an eyedropper reads rendered pixels, which can be altered by compression, anti-aliasing, color-profile conversion or gradient blending. A file's extension alone does not confirm that it contains editable vector paths, so check the actual objects in a vector editor before trusting a sampled value.

Identifying a logo's color does not grant permission to reuse it. Being able to download a logo file is separate from having the right to modify the artwork, use its fonts or use the trademark itself.

RGB is for screens, not final print values

RGB describes color for displays. Printed logo deliverables typically need CMYK or spot-color values, and converting RGB 0, 100, 0 to those systems depends on the color profile and printing conditions. No verified CMYK or spot-color equivalents were supplied for this article, so specify print values with your printer or from the brand's official guidelines rather than relying on an automatic conversion.

Gaps in the available evidence

No source material was provided for any specific brand's dark green, for verified print conversions, or for accessibility contrast results against particular background colors. The values in this article are limited to the documented CSS named colors and the arithmetic that relates RGB to hex notation.
