The T1X5 project consists of a set of five equilateral triangular canvases, each measuring 50 cm in height. The paintings are constructed on an isometric grid in which each triangular unit measures 5 cm, establishing a strict and coherent structural framework. 

The series explores the confrontation between black and four distinct shades of grey, ranging from 100% (black) to 80% in 5% increments, articulated through horizontal bands. 

Through this graduated system, the work examines perception, contrast, and variation within a rigorously defined monochromatic sequence.
