PROPERTIES RELATED TO COLOR
In HTML code, you can refer to colors in several ways – by name, RGB value, hexadecimal value, or
“short hex” value. HTML uses 216 colors; however, of the 216, only 16 colors are considered to be
“Web safe,” meaning that they are designed to be displayed the same.
RGB VALUES | are based on the intensity of red, green, and blue. Each RGB letter is represented
by a value from 0-255. The three RGB values are often referred to as RGB triplets.
HEXADECIMAL VALUES | are used for colors to represent the intensity of the red, green, and blue.
In hexadecimal, 00 is the lowest intensity and FF is the highest. The hexadecimal number is
preceded by a flag character (#).
