title: how to change default color scheme without mess up vi's color
body: <p>Hey guys
  I recently moved to macvim, It's great, when I add the theme: torth in the .vimrc. I found the color vi totally changed, It's either  the way of rails plugin, or the torth, like mixed color.</p>
  
  <p>so how to set the startup color only affect macvim, I'm familiar with the vi's color with rails plug in, I don't want to mess it up.</p>
  
  <p>BTW I how to toggle off the top tool bar in start up, It would be great,if someone can show me where to find the whole setup instruction.</p>
  
  <p>Thanks</p>
