Vundle Plugin update log font color scheme.

[AmeyaVS]

From recent updates currently after updating the Plugins If I open the update log by pressing 'u'.
One can notice that some of the messages font color scheme are too close to the background for the text to be visible.

I have attached the screen-shot. Encircled in red oval is the text which I have highlighted using visual mode in vim. If one doesn't highlight the text it becomes totally unreadable as it matches the background color of the terminal window.

I have seen similar behaviour on Windows GVim, Cygwin vim and in Linux shell also.

Note: Mostly the text is invisible when the log displays merge messages.

Kindly let me know if one can change the color scheme for the log messages.
