<p dir="auto">Hi<br>
This is a suggestion.<br>
bootstrap is one of a wonderful project that I've seen but i think if the customize page has a little features it becomes more wonderful<br>
I don't know what colors in the fields look like in customize page in getbootstrap.com and i have to copy paste that HEX code to see what is the color of them then change it while if you put a little div box beside each field to shows the color it was very useful<br>
Or better than this is  put a color picker something like this:<br>
<a href="http://twitterbootstrap3navbars.w3masters.nl/" rel="nofollow">http://twitterbootstrap3navbars.w3masters.nl/</a></p>
<p dir="auto">Then we customize the color and see what is output then compile it<br>
I think this page doesn't use more</p>
<p dir="auto">Thanks</p>
<p dir="auto">Using javascript to automatically update a small preview for colour variables on the customiser (perhaps using input groups).</p>
