Alkaline earth metals dissolve in liquid ammonia to form ammoniated cations and ammoniated electrons. The reaction is given by:

$M+(x+y)N{H}_3\to [M(N{H}_3{)}_x{]}^{2+}+2[e(N{H}_3{)}_y{]}^{-}$

The presence of ammoniated electrons imparts a deep blue black colour to the solution.

Answer: Deep blue black
