Probable you think to hexaamminocobalt chloride: the color is orange.
Cobalt does not react with water at room temperature. However, finely powdered cobalt can react with water over time to form cobalt hydroxide and hydrogen gas.
Alkali metals react with ammonia liquid to form metal amides and ammoniated electrons. These ammoniated electrons are responsible for absorbing energy from visible light, leading to a deep blue color in the solution. This phenomenon is known as charge transfer complexes.
Cobalt (II) chloride dihydrated (purple colour) and with more water Cobalt (II) chloride hexahydrated (pink colour) .
yesssssssssssssssssssssssss :DDD of course it does !!
No, they will not because their anions are same i.e. Nitrate

Yes ammonia can react with aluminum oxide. Aluminum oxide is ampoteric, that is, it shows both acidic and basic characters. Ammonia is basic in nature, so there will be a reaction between acidic and basic chemicals.
pink
Radioactive or not, pure cobalt is a gray metal.
all cobalt (+ 2) salts are red but with sulphate cobalt shows pinkish red colour.....
Aqueous ammonia is colorless.
The balanced equation for the reaction between cobalt chloride (CoCl2) and ammonia (NH3) would be: CoCl2 + 6NH3 → [Co(NH3)6]Cl2

Red cobalt
It is colorless.
