However, there are still important works from this period, because Obregón was undoubtedly a talented and imaginative painter. It is obvious that he is at his best when he controls his effusiveness and maintains his mastery of each brushstroke, as well as the colors. Obregón made numerous works that dealt with violence in Colombia, from the 1948 oil painting Masacre 10 de abril (April 10 Massacre) to the acrylic diptych of 1982, Muerte a la bestia humana y Victoria de la paz (Death to the Human Beast and Victory of Peace), executed after the murder of Gloria Lara, to the 1962 oil painting Violencia (Violence), of which Marta Traba wrote: "The terrible sincerity of Violence comes from this: that Obregón painted it because it could no longer be postponed and it was necessary for him to do so. But if this explains the true pathos of his painting, it does not account for the serious and tense beauty of his means of achieving it. Obregón painted the reclining woman in the midst of a large gray space: he solemnly modulated the gray, as if officiating a silent funeral rite, without allowing it a single discordant note. He squeezed it into the enormous gravid figure and unwound it into the landscape, until the dead creature was integrated into that generalized sadness, into that iniquitous, inexplicable fatality.” In addition to his innumerable easel paintings, Obregón created several murals.**
