en.wikipedia.org/wiki/Copper(I)_oxide

Copper(I) oxide or cuprous oxide is the inorganic compound with the formula Cu 2 O. It is one of the principal oxides of copper, the other being CuO or cupric oxide. This red-coloured solid is a component of some antifouling paints. The compound can appear either yellow or red, depending on the size of the particles.

Copper(II) oxide or cupric oxide is the inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu 2 O or cuprous oxide.As a mineral, it is known as tenorite.It is a product of copper mining and the precursor to many other copper-containing products and chemical compounds.

Variation among individuals was marked but the highest liver copper concentration recorded (7.59 mmol/kg dry matter) produced no biochemical evidence of copper toxicity. Cupric oxide particles were separated into three fractions, clumps, short rods and long; and 5 mg/kg live weight of each fraction given to steers of 173 kg mean live weight.

Students heat copper(II) oxide in a glass tube while passing methane over it. The copper(II) oxide is reduced to copper. If the reactants and products are weighed carefully the formula of the copper oxide can be deduced. This could also be used simply as an example of reduction.

First of all CuO or copper oxide is black in colour. It is actually a Salt. CuO is a very important reagent in the laboratory. It has many uses like proper disposal of some organic and inorganic compounds( cyanide, etc.,.) and it is also used to preserve wood too.

The copper hasn't changed color, but its surface has oxidized. If metallic copper is still visible through the oxide film, you see the so-called 'interference colors' which are a function of film thickness. When light hits the oxide, a portion reflects off its top surface and the remainder passes through to the metal and reflects.
