用frameset写的框架，框线怎么改颜色？

白色的框线怎么改变颜色，默认的白色太难看，来个大神指点一下一啊/凑字数凑字数凑字数凑字数凑字数凑字数/

 <frameset cols="25%,50%,25%" bordercolor="border-color:red;">

请参考FrameSet框架网页_百度文库
http://wenku.baidu.com/view/01d74653ad02de80d4d840a5.html

 <frameset rows= "69,* " cols= "* " border= "0 " frameborder= "1 " framespacing= "5 " > 
<frame src= "index_top.jsp " name= "topFrame " scrolling= "NO " noresize frameborder= "no " bordercolor= "#CADAE8 "> 
<frameset cols= "160,* " frameborder= "1 " framespacing= "5 " > 
<frame src= "index_left.jsp " name= "leftFrame " id= "leftFrame " scrolling= "NO " frameborder= "no " bordercolor= "#CADAE8 "> 
<frame src= "index_main.jsp " name= "mainFrame " id= "mainFrame " frameborder= "no " bordercolor= "#CADAE8 "> 
</frameset> 
</frameset>

直接写在frameset上样式啊，
