retrieve variables from txt file and run command

Dear all,

I have a macro, helping to annotate images with scale bar, channel
names, doing a montage and so on. So far, the initial dialogue gives the
user several options, and is filled with default values.

I like to have a text file with those variables and recall them
automatically when the Macro is started, and yes, that works.

setOption("ExpandableArrays", true);

mp = getDirectory("macros");
pathset = mp+"CnZsettings.txt";
     string2 = newArray();
     file = File.openAsRawString(pathset);
     delimiter= '\n';
     string2 = replace(file, delimiter, "@");
     values = newArray();
     values = split(string2, "@");

However, when taking the value from the text file (e.g. Green) and
assigning to a variable:

a=values[0];

the run(a); or SetColor(a); to change either the channel colour or the
foreground colour don't work, giving me /Unrecognised command: "Green"/.
Retrieving however numerical values from the same .txt file and using
them e.g. for the scale bar do work.

Do you have any suggestion where to look for a solution? I believe that
I somehow have to change the "type" of the variable or something?

I already tried a="\""+values[0]+"\""; but this didn't work, giving me
/Unrecognised command: ""Green""/.

I am very happy if one of you could help me.

Best,

Chris
