In cperl-mode I am able to change the array and hash faces with M-x customize-group RET cperl-faces RET, and change Cperl Hash Face and Cperl Hash Face. But I can not see any option for changing the scalar variables color. 
I have tried to change font-lock-variable-name-face both inside the code or from Cperl Ps Print Face Properties (where I really want to change the color is in the print) but It does not work. I have tried several cperl-modes from 4.32 to the rockway-perl6-branch.
Also I would like not to have the $ colored in the variables, therefore the sigil would stand out better in the printouts (this was asked already here but not resolved).
could someone provide me any hints?
