I conducted some experiment and I want to know the resulting redish black thing
Solvated copper(II) ions for the blue color, copper(II) oxide for the black (as hinted by IvanNeretin). To prove this hypothesis, one could dissolve the copper oxide in sulphuric acid, neutralize the solution and add ammonia. The deep blue color indicates the $\ce{[Cu(NH3)4(H2O)2]^{2+}}$ complex. The latter can also be done for the blue solution currently present.
