Expressing Colors in CSS Hex Triplet: –Using color names is handy and easy to understand, but most computer screens today are capable of displaying over 16 million colors. –We identify them using a hex triplet. A hex triplet is a six-digit number, where each pair of digits represents (in order) the value of red, green, and blue.

Expressing Colors in CSS Each pair of digits is a hexadecimal number (base 16), where 00 is the lowest value and FF is highest. Here are some examples: –#FF0000 has the maximum amount of red, but no green or blue (result: red) –# mixes a lot of red, no green, and a lot of blue (result: darkish purple) –# has no color (result: black) –#FFFFFF has maximum amounts of all colors (result: white)
