Born in Río Cuarto, Córdoba, Colotto started his professional career with Estudiantes de La Plata, making his Primera División debut on 16 February 2001 in a 1–1 draw against Club Atlético Vélez Sarsfield and eventually becoming an automatic first-choice with the La Plata club. In December 2004, Tecos F.C. from Mexico paid US$1,100,000 for his services and, almost three years later, he was signed by another team in the country, Club Atlas, playing nearly 150 competitive matches between the two.
On 30 August 2008, Colotto signed for Deportivo de La Coruña in Spain, for €2.5 million. In his first season in La Liga he backed up Alberto Lopo and Zé Castro but, on 2 October, scored twice against SK Brann in the first round of the UEFA Cup: after the Galicians lost 0–2 in Norway, his brace – after heading home two corner kicks – took the game to extra time and an eventual penalty shootout, where the home team prevailed to reach the group stage.
In the following seasons, Colotto relegated Portuguese Castro to the bench and partnered Lopo at the heart of the back sector, under Miguel Ángel Lotina. In the 2009–10 campaign two of his three league goals came in both matches against CD Tenerife (1–0 away, 3–1 at the Estadio Riazor) as Deportivo finished tenth.
On 22 June 2012, free agent Colotto joined fellow league team RCD Espanyol on a three-year contract. In 2013–14, he equalled a career-best four goals as the Catalans narrowly avoided relegation.
Colotto spent the 2015 season in the Indian Super League, with FC Pune City. In February 2016, at nearly 35, he returned to his country and agreed to a six-month deal at Club Atlético Lanús with the option of further extending it.
Colotto spent the 2016–17 campaign with Quilmes Atlético Club, acting as team captain and eventually suffering relegation to the Primera B Nacional. He was then released on 19 July 2017 alongside six players as the board of directors feared injuries that would imply that the contracts be automatically renewed, only to return the following month and put pen to a paper to a new contract.
Colotto was part of the Argentina under-20 team that competed at the 2001 FIFA World Youth Championship on home soil. He played all the matches and minutes for the eventual winners during the tournament, scoring in the final against Ghana (3–0).
