Setting shelf image to transparent?

[Lovejonze]

Hi,

First of all I'd just like to say thanks to all who have contributed to this fantastic project - awesome work.

As a newbie I've found Baker Framework really easy to work with but would really appreciate a little help in customising the shelf interface. Basically, I'd like to make the issue placeholders in the gridview use a transparent background.

It seems that the background colour comes from colorWithHexString in IssuesViewController.m reading from UIConstants. I don't think hex codes can handle alpha transparencies so any suggestions on how I could change this to use a CSS string?

Thanks in advance, Mike.
