Little correction to marc-gutt's regural expression to validate hex color values. You can use
this little function:
<?php
// Validate an hex color string. Return true if valid, false otherwise
function validateHexColor($color) {
$color = substr($color, 0, 7);
return preg_match('/#[0-9a-fA-F]{6}/', $color);
}
?>
