Hi, i don’t know if i understood correctly.
These are simple color blocks & text created in AE (so would it even possible to be above 1 ?)
Color (R/G& B) close to 0. Alpha 0,8.
So bluish black blocks with transparency 80 + white text on the block (1/1/1).
Good thing to know, that the working space has to be set to linear in AE at the start of the project if it has to be rendered for FCP X !
Thanks a lot !
