Sign character background not the same the the column background

Question

In my vim the signs character background is not the same that the SignColumn background.

It is quite disruptive, so what could I do to correct it ? Is there any particular :highlight command to change my signs background and to solve it ?

Answer 1

Each sign is defined to use a specific syntax highlight group for its text. See :help :sign-define. Find where the sign is defined, check the "texthl" part of it, and either change that part or change the highlight attributes of that highlight group.
