(29 December 1876 – 24 October 1968) was a member of Paris Foreign Missions Society and the last missionary archbishop of Archdiocese of Pondicherry.

Then he entered the joint minor Seminary of Notre Dame des Champs.

Desiring to become an official in the French army, for his secondary education he entered Lycée privé Sainte-Geneviève under the care of Jesuits.

He arrived at Pondicherry on 18 August 1900, and was appointed Professor in seminar-College, under the strict direction of Father Elisabeth.

Colas was named Archbishop of Pondicherry, succeeding Bishop Elie-Jean-Joseph Morel who gave his resignation for health reasons.

Archbishop Ambrose Rayappan, priest of the diocese of Coimbatore, was consecrated by Msgr.

In 1932, he opened a new minor seminary at Cuddalore, which was then the headquarters of South Arcot district in the British territory.

In India, looking at the Indian Bishops at the head of Bangalore, Coimbatore, Kumbakonam, Salem and most probably very soon in Pondicherry, our Society can confirm that it has fulfilled the intention of its founders.

He therefore left it to his coadjutor, Bishop Ambrose and went to withdraw at the Pavillon St Augustin's Hospital Ste Marthe in Bangalore.

His mortal remains were transported to Pondicherry, and the funeral mass was said by nine bishops and archbishops along with the priests of the diocese, and thousands of diocesans.
