Yes, but the problem is that I want to put colors as parameter, in order to change the colors once my report will be stored in our intern server, so I have to put all the colors in this parameter, but I don't know how to do it and which expression I have to write

I uesed this one: =Parameters!Colors.Value, but in this case, I have to put all the colors manually in the " avalibale values of parameters". I am looking for a special expression which contains all the colors
