I would like to make my
listings environnements more readable by coloring the background of some keywords with a specific color. Like this :
I thought using the
\colorbox function from
xcolor package but It only work with an argument (not as
\color) and doesn't work with listings.
Is there another way to get colored text background working with
listingsallows for setting keywordstyles and also has a mechanism for escaping to LaTeX. However, it is rather unclear to me how you want to use it. (E.g., the picture you posted doesn't look at at like a listing!)
