bbcode

I'm trying to parse BBcodes in php but i don't think my code is safe at all.

$Text = preg_replace("(\[color=(.+?)\](.+?)\[\/color\])is","<span style=\"color: $1\">$2</span>",$Text);

I think you can pass an injection like this and it will work:

[color=<script>alert('gotcha');</script>]

How to improve my regex to only capture the two standar color formats:

[color=red] OR [color=#FF0000]

Thanks
