About Dark Slate Gray
Dark Slate Gray (darkslategray) is a dark, moderately saturated cyan with the hex code #2f4f4f, or rgb(47, 79, 79). In HSL it sits at a hue of 180°, 25% saturation and 25% lightness. CSS also accepts the spelling darkslategrey for exactly the same color. It is one of the 148 named colors every browser understands, so you can write color: darkslategray; instead of the hex value.
