Procedural pattern reconstruction made in Substance Designer and rendered with Blender 4.2 (Cycles).
This one is based on pattern designed in 1959 for Bilbille & Co - Parisian textile firm, that specialized in woven printed silks and rayons, and produced color charts for wool and other fabrics, particularly in the mid-20th century. They are mostly known for their vintage color charts for various fabrics, including a 1956 wool color card. Unfortunately I wasnt able to find the original name of the pattern as well as original designers name.
This pattern is avaliable as part of my Pattern Collection for CG Visualisation which is avaliable on Blender Market:
