Todos los colores se forman a partir de tres básicos: rojo, verde y azul (red, green, blue, RGB).
Cada código HTML comprende el símbolo «#» seguido de una combinación de 6 números hexadecimales.
Los números hexadecimales, se forman utilizando 16 dígitos (en lugar de los diez de la numeración decimal habitual).
Estos dígitos, de menos a más cantidad de color, son: 0 1 2 3 4 5 6 7 8 9 A B C D E F.
Por ejemplo, «FF» en hexadecimal representaría el número 255 en numeración decimal.
La intensidad de cada componente se expresa como un número hexadecimal del 00 al FF (del 0 al 255 en base diez).
La combinación de rojo, verde y azul (cada uno del 0 a 255), ofrece más de 16 millones de colores diferentes (256 x 256 x 256).
El color rojo se representa como #ff0000, porque tiene toda la intensidad de rojo y nada de verde y azul.
El color verde se representa como #00ff00, porque tiene toda la intensidad de verde y nada de rojo y azul.
El color azul se representa como #0000ff, porque tiene toda la intensidad de azul y nada de verde y rojo.
El color blanco es la mezcla de todos los colores: #ffffff.
El color negro representa la ausencia de color, por tanto su valor será #000000.
Para hacer un color más oscuro, hay que reducir la intensidad del componente principal, dejando los otros dos iguales.
Así, el rojo (#ff0000) se hace más oscuro así: #cc0000, #990000, #660000, #330000, etc.
Para hacer un color más pastel (más claro), hay que variar los otros dos colores dejando igual el principal.
Así, el rojo (#ff0000) se hace más claro asi: #ff3333, #ff6666, #ff9999, #ffCCCC etc.
