If you reverse the screen colors on your monitor on long days of coding it is much easier on the eyes. This is a representation of the default settings of the colors in BBEdit reversed and tweaked slightly for optimization.
Copy and create the file Reverse_Colors.bbcolors to location
~/Library/Application Support/BBEdit/Color Schemes
If this location does not exist create it, restart BBEdit, then drop this file in the directory.
To initialize the color file, open preferences > text colors at the top of the right column there is a drop down, select Reverse_Colors
You may want to make minor adjustments for you lighting conditions, monitor settings etc.
