I may be off on the details, as I don't have time to refer to the
custom-toolbar-icon part of the iOS Human Interface Guidelines document. You
can do that yourself.
The color of the icons doesn't affect how they are displayed. The icon is drawn
by alpha, not color. If you feed in an opaque square, no matter what's been
painted onto it, the icon will show up as a square. I seem to remember that
they recommend white-on-transparent, but I've seen nothing wrong from
black-on-transparent icons.
