tinymce span style color not working

hi all

I m using tinymce for adding content to my website.

also i m using

$detail = mysql_real_escape_string('$detail');

When ever i select text and change its colour, tinymce add <span> tag to it with a slash in style attribute.

This is what is getting added to my database

<p><span style=\"color: #3366ff;\">Feel free to try</span> out the different features that are provided,</p>

When i echo it on my detail page

echo $detail;

then the style color doesnt get applied on the text.

what should i do to echo the text in colored format.
