Any "easy" way to change ghost entity colors?

[Taurondir]

I was messing around with the shader files in 0.18 and had managed to change it to another color without needing a mod on the server or effecting anyone elses game, but with that same file in Factorio v1.0 (sprite-ycocg.frag) ... cant figure out what to change, as apparently I have no idea what I'm doing other then trial and error.

I want to make them more easy to spot as right now unless I zoom in and STARE at the screen I can't spot them among placed entities.

The shader "hack" made them red - but also made a few other things red, like the Roboport "range highlight", but .... *shrug*, and only effected my client anyway, as Shader files changes dont cause "your game is different" error messages.
