HTML$,$ the markup language of the web, specifies colors using the RGB model. It uses a two$-$digit hexadecimal $($that is$,$ base $16)$ representation for each component

of the vector, and concatenates the three numbers together to form one large, six$-$digit number. For instance, the HTML color code #$80$FF$3$B has red component $80,$

green component FF$,$ and blue component $3$B$.$

In hexadecimal, the digits $0$ through $9$ have their usual meanings, but the letters A through $F$ also function as digits, and have the meanings $10$ through $15,$

respectively. Because hexadecimal means base $16,$ a two$-$digit number such as $3B$ thus has the meaning $16*3+11=59.$ The $16$ is used because the $3$ is in the

$16$ s place, and the $11$ is the meaning of the digit B$.($If you found this introduction to hexadecimal notation too brief, consult the web for more details.$)$
