a solution for the described problem ("HaEtz Ha'adom Beyoter") will be a MST with maximum number of red edges ?
or just a regular spanning tree with maximum number of red edges ?

Is it possible for my tree to have 0 red edges? Can I take for a counter-example such a graph that has red&black edges, and that if any tree of his will take ANY of  the red edges the tree will not be an MST?

If it proves the algorithm is wrong, then yes, you can.
