In computing, on the X Window System, X11 color names are represented in a simple text file, which maps certain strings to RGB color values. It was traditionally shipped with every X11 installation, hence the name, and is usually located in <X11root>/lib/X11/rgb.txt. The web colors list is descended from it but differs for certain color names.

Lavender is a light shade of purple or violet. It applies particularly to the color of the flower of the same name. The web color called lavender is displayed adjacent—it matches the color of the palest part of the flower; however, the more saturated color shown as floral lavender more closely matches the average color of the lavender flower as shown in the picture and is the tone of lavender historically and traditionally considered lavender by average people as opposed to website designers. The color lavender might be described as a medium purple, a pale bluish purple, or a light pinkish-purple. The term lavender may be used in general to apply to a wide range of pale, light, or grayish-purples, but only on the blue side; lilac is pale purple on the pink side. In paints, the color lavender is made by mixing purple and white paint.

In optics, orange has a wavelength between approximately 585 and 620 nm and a hue of 30° in HSV color space. In the RGB color space it is a secondary color numerically halfway between gamma-compressed red and yellow, as can be seen in the RGB color wheel. The complementary color of orange is azure. Orange pigments are largely in the ochre or cadmium families, and absorb mostly blue light.
Varieties of the color green may differ in hue, chroma or lightness, or in two or three of these qualities.

Shades of brown can be produced by combining red, yellow, and black pigments, or by a combination of orange and black—illustrated in the color box. The RGB color model, that generates all colors on computer and television screens, makes brown by combining red and green light at different intensities. Brown color names are often imprecise, and some shades, such as beige, can refer to lighter rather than darker shades of yellow and red. Such colors are less saturated than colors perceived to be orange. Browns are usually described as light or dark, reddish, yellowish, or gray-brown. There are no standardized names for shades of brown; the same shade may have different names on different color lists, and sometimes one name can refer to several very different colors. The X11 color list of web colors has seventeen different shades of brown, but the complete list of browns is much longer.
Shades of black, or off-black colors, are colors that differ only slightly from pure black. These colors have a low lightness. From a photometric point of view, a color which differs slightly from black always has low relative luminance. Colors often considered "shades of black" include onyx, black olive, charcoal, and jet.
Shades of chartreuse are listed below. Chartreuse is a color between yellow and green, so named because of its resemblance to the color of the French liqueur green chartreuse.
