Unsolved Mumble : color of user/channel

[Morph]

HI,

Sorry for my english,

I try to explain my little problems.

I want to have a differente color for my client mumble to channell/user.
Exemple :

channel1 (color red)

• user1 (blue)
• user2 (blue)
  Channel2 (color red)
  -user3 (blue)
  -user4 (blue)

my code :

QTreeView::branch {
background: transparent;
image: none;
}
QTreeView::branch:has-siblings:!adjoins-item {
image: url(skin:designs/branch.png);
}
QTreeView::branch:has-siblings:adjoins-item {
image: url(skin:designs/branch_more.png);
}
QTreeView::branch:!has-children:!has-siblings:adjoins-item {
image: url(skin:designs/branch_end.png);
}
QTreeView::branch:closed:has-children:has-siblings,
QTreeView::branch:has-children:!has-siblings:closed {
image: url(skin:designs/branch_closed.png);
}
QTreeView::branch:open:has-children:has-siblings,
QTreeView::branch:open:has-children:!has-siblings {
image: url(skin:designs/branch_open.png);
}

I don't find how to put my color user diffrently color channel.

Can you help me.
