Passing A String Into The InsertCommand Of SqlDataSource At The @color Character

Ok, so I'm a JSP guy and thing it should be easy to replace "@color" with t_color after I initialized it to red by
        String t_color = "red";
and then calling the insert

        SqlDataSource1.Insert();
here is insert command: 
            InsertCommand="INSERT INTO [favcolor] ([name], [color]) VALUES (@name, @color)" 
 
I've tried       InsertCommand="INSERT INTO [favcolor] ([name], [color]) VALUES (@name, "+ t_color+")"
 
Ive tried        InsertCommand="INSERT INTO [favcolor] ([name], [color]) VALUES (@name, "<%$ t_color %>" )" 
 
Is there any easy way to do this?
 
or
 
Can I set it like
 
@color = t_color?
 
 
Thanks in advance for ANY help
 
JSP turning ASP (Maybe)
