Changing the font color of the antispam question

[Ashraf]

How can I change the color font of the antispam question only whithout changing the color of the rest of the text?
In the customized CSS I created:
div.userpro {
color: #FFF;
}

Is changing the color for everything which makes the antispam question unvisible.

Any Help please
