You can change laser color and opacity for yourself and enemy snipers. Also has Rainbow Laser option now.
Originally made by Seven and converted to BLT by Iron Predator. Basically this but with an ingame menu (in options > mod options).

If you don't know how RGB values result in a color you might want to have a look at this or simply keep trying.

Known Issues:
- Changing things in the menu while in a heist will not refresh the laser color until the next heist/day of a heist is launched

Kudos to TdlQ and Offyerrocker for letting me steal helping me with some code.
