I have a language editor that i have developed using XText grammar. Now i want this Editor to grey out (background color to grey) the first 10 characters in a line.

Is this possible in Xtext? If yes, how can i approach this issue?

As a starting point see Semantic Highlighting section in https://eclipse.org/Xtext/documentation/310_eclipse_support.html#highlighting

You would have to traverse the node model, identify line beginnings and accept hightlighted ranges.
