In an attempt to make the BT game more friendly to people with color blindness, I (with the help of @gponick) have made a new release that allows you to setup multiple sets of colors to deal with various landscapes. This is great if you're not color blindness because the default colors can hardly be seen on martian style planets. Also I've added the ability to dash any of the parts of the line of fire lines (direct, indirect, and obstructed).
I had to add new mod settings to the mod.json in a new format, but your old mod.json file's settings will still work for now.

Anyway, here's an example image of a blue indirect fire line on an ice planet at night normally and with simulated full color blindness.
Super difficult to see in either. So now there's a keybind for changing to the next set of colors.
And a demonstration with direct line of sight…
I'm still working on a couple ideas to help that look like this.
