Usando pseudo-clases CSS:even y:odd con elementos de lista

¿Es posible usar pseudo-clases CSS en elementos de lista?

Esperaría que lo siguiente produjera una lista de colores alternos, pero en su lugar obtengo una lista de elementos azules: 

<html>
    <head>
        <style>
            li { color: blue }
            li:odd { color:green }
            li:even { color:red }
        </style>
    </head>
    <body>
        <ul>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
        </ul>
    </body>
</html>

El problema con su CSS radica en la sintaxis de sus pseudo-clases.

Las pseudo-clases pares e impares deberían ser: 

li:nth-child(even) {
    color:green;
}

Y

li:nth-child(odd) {
    color:red;
}

Usa esto: 

li { color:blue; }
li:nth-child(odd) { color:green; }
li:nth-child(even) { color:red; }
