![]() ![]() Modern technologies use RGB color values and may or may not use hex values to represent them. ![]() However, the RGB system predominates in purely digital image representation. A different color system known as CYMK or cyan, yellow, magenta and black, is used for managing color printing. It's important to note that the RGB color system is not the only color system used in the world of technology. Also, new technologies often abstract both the binary and the hexadecimal value by using a color name based on those values, for example, in cascading style sheets to universalize themes and styles on the web. It’s worth pointing out that with possible permutations of 0-256 ranges for each of the three color values, red, green and blue, the system yields 16,777,216 results, which is more colors than the human eye can actually distinguish. In that sense the octet was a reasonable way to represent these types of values. It's also possible to expand that six-digit value back to its individual RGB value.Īnother reason that hexadecimal color values took off is that many machines used 8-bit operational codes. In that sense, it compresses the individual RGB values into one six-digit value that uses a combination of alphanumeric characters including letters and numbers to identify a color. One way to show a color’s composition would be to list all three of the red, green and blue values.īecause red-green-blue values each range from 0 to 255, the resulting code would be nine characters long.īy contrast, the hexadecimal format is only six characters long. ![]() These color hex codes have been an integral part of HTML for web design, and remain a key way of representing color formats digitally. ![]()
