Hexadecimal codes are used to represent colors in HTML, with six-digit sequences of numbers and letters indicating varying levels of red, green, and blue intensity. Common color schemes include monochromatic using one color with variations, complimentary using two colors that complement each other, and others like elegant, eye-catching, chic, and organic. Resources for determining safe and effective color combinations include color code websites and guides to web design.
