He is the son of Franco Colomba, who brought Davide to Parma F.C. when he had been head coach there in summer 2011. Parma swap the registration rights of Colomba to 50% registration rights of Francesco Pambianchi and Alessandro Vecchi directly, for €450,000 nominal value in accounting. The profit did not prevent the fold of SPAL.
On 14 July 2011, he joined Crotone on loan for the 2011-12 campaign.
In June 2012 Parma bought half of the registration rights of Lorenzo Pasqualini for €1.25 million with Colomba moved to Ascoli for €1.1 million, thus only €150,000 cash involved.
