The code seems to fix the color and is working without any issues.
Somehow default raidframe related stuff is always a bit messy.
I get the color and gradient/effect stuff but I still dont understand where the texture (length/size) came from
Maybe I am missing something and its just color but I am a bit confused because for shield/absorb theres a Raidframe Texture called "Shield-Overlay".
It would be pretty nice if I could change the white-texture to my statusbar/health-texture like the rest of my UI.
It is the same texture as everything health related like: Interface/RaidFrame/Raid-Bar-Resource-Fill.blp
If that is even possible without making a mess.
Again thanks for all the help
