While working with super-duper piece of software Coda, I felt that its native look could be a little more personalised. As a result small collection of .sseestyle themes (codename Blue River) has been born. You are free to download, use and modify it from here: Blue River seestyle for Coda 0.1.
As I’m mostly working on CSS, HTML and PHP files, only those three modes are included in the package. For the installation open the Preferences menu in Coda, click on the Colors tab and import preferred files.
