makes the plasma visor overlay a lighter color and also actually work for modsuits (#88751)

## About The Pull Request

the module doesn't actually show the visor thanks to the fact that the
module is not actually active at any point, which the visor attempts to
check for

also the color of purple was like WAY too dark it was practically black
on every modsuit
## Why It's Good For The Game

it'd be cool if it actually worked and you could actually see it
## Changelog

fix: fixes plasma stabilizer module not showing a visor on modsuits
