Gogo loves English. Workbook 5 lesson colors The following is a list of colours. A number of the color swatches below are taken from domainspecific naming schemes such as X11 or HTML4. RGB values are given for each swatch because such standards are defined in terms of the sRGB color space. It is not possible to accurately convert many of these swatches to CMYK values because of the differing gamuts of the two spaces, but the color management systems built into operating systems and image editing software attempt such conversions as accurately as possible. The HSV (hue, saturation, value) color space values, also known as HSB (hue, saturation, brightness), and the hex triplets (for HTML web colors) are also given in the following table. Colors that appear on the websafe color palette—which includes the sixteen named colors—are noted.1 (Those four named colors corresponding to the neutral grays have no hue value, which is effectively ignored—i.e., left blank.)
