What are the theme variables for line added/removed when suggesting changes ?

[tito]

Here is an example on One Dark. I tried all the variables, i cannot find the one that control the color of the modified/added line.
There is a red color for the line deleted, and no color for the line added/changes.

Can somebody point out which one are actually used ?
I tried all the one in One Dark, but cannot pin point which one it is.
