What color is the binder for pairs 51-75 in a 100-pair cable?

In a 100-pair cable, the pairs are organized into four 25-pair binders, each with a distinct color to make it easy to locate the right block. The common sequence is blue for 1–25, orange for 26–50, green for 51–75, and brown for 76–100. This color-coding helps technicians quickly identify the correct group when wiring, testing, or repairing circuits. So, for the block that contains pairs 51 through 75, the binder color is green.
