Rufous ( // ) is a color that may be described as reddish-brown or brownish-red, as of rust or oxidised iron. The first recorded use of rufous as a color name in English was in 1782. However, the color is also recorded earlier in 1527 as a diagnostic urine color.
The word "rufous" is derived from the Latin rufus, meaning "red", and is used as an adjective in the names of many animals—especially birds—to describe the color of their skin, fur, or plumage.
Vermilion is a color, color family, and pigment most often made, since antiquity until the 19th century, from the powdered mineral cinnabar and its corresponding color. It is very often synonymous with red orange, which often takes a modern form just 11% brighter.
Beige is variously described as a pale sandy fawn color, a grayish tan, a light-grayish yellowish brown, or a pale to grayish yellow.

It has come to be used to describe a variety of light tints chosen for their neutral or pale warm appearance.

This gives a yellow tone to otherwise-white milk at higher fat concentrations. Cream is the pastel colour of yellow, much as pink is to red. By mixing yellow and white, cream can be produced.
Red-violet refers to a rich color of high medium saturation about 3/4 of the way between red and magenta, closer to magenta than to red.

Orange pigments are largely in the ochre or cadmium families, and absorb mostly blue light.

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.
Azure is a variation of blue that is often described as the color of the sky on a clear day.
