Answer 2

Answer:

Shades of brown can be produced by combining red, yellow, and black[1] pigments, or by a combination of orange and black—as can be seen in the color box at right. In the RGB color model used to create all the colors on computer and television screens, brown is made by combining red and green light at different intensities. Brown color names are often not very precise, and some shades, such as beige, can refer to a wide variety of colors, including shades of yellow or red. 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 the one name (such as beige or puce) can refer to several very different colors. The X11 color list of web colors lists seventeen different shades of brown, but the complete list of browns is much longer.

Brown colors are dark or muted shades of reds, oranges, and yellows which are created on computer and television screens using the RGB color model and in printing with the CMYK color model. Browns can also be created by mixing two complementary colors from the RYB color model (combining all three primary colors). In theory, such combinations should produce black, but produce brown because most commercially available blue pigments tend to be comparatively weaker; the stronger red and yellow colors prevail, thus creating the following tones. Below is a list of some of the common brown colors.
