Cell background and accessory

I am trying to set the cell background of my UITableViewCells but I am struggling with the background color of the UIAccessoryView. It does not change.

Can anyone help me make the background color of the UIAccessoryView transparent (or actually any other color)?

This is my code

cell.textLabel.backgroundColor = [UIColor clearColor];
cell.accessoryView.backgroundColor = [UIColor clearColor];
cell.detailTextLabel.backgroundColor = [UIColor clearColor];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;

if(indexPath.row % 2) {
     cell.contentView.backgroundColor = [UIColor clearColor];
}
else {
    cell.contentView.backgroundColor = [UIColor redColor];
}

Here is an image illustrating the issue
