Distractive unchecked box

[TexDash]

First I like this theme very much, and thank you for this great work!

I found that the red color of the uncheck box is a little annoying and distractive, since most people tend to focus only on the checked box in their first glance of the dialog. But our current red color forces the users to pay more attention to the unchecked ones ... One possible improvement is changing the red color to some others (gray or light blue etc).
