volume icon doesn't inherit KDE colorscheme

[demoy]

Hello, I was using one of the many derivatives of your lovely theme I notice the volume icon seemed wrong. I changed to the original la capitaine and it seems like the volume icon became doesn't follow the colorscheme. You two did such a great job the last time around so maybe its from a later commit.

I found 2 others: lock and unlock

I believe the icons are player-volume.svg, document-encrypted.svg and document-decrypt.svg in actions, but I don't see any fault fault them.

As a programmer I recognize how frustrating it is to try and fix something you can't see and don't use.

EDIT: even more.

I'm going to hard set the color in my locale copy to my theme color. Not sure if I should close this issue or not. you decide.

@demoy let's keep this issue open for now, if you can provide a list of non-conformant icons in a comment on this issue, I can try to fix them as was done the last time this issue was pointed out about a year ago. Cheers!
