Why do the renal columns and renal cortex appear similar in color and texture?

The kidneys have different layers of connective tissue. The connective tissue in the kidney connects different organs within the kidney. Connective tissue has the same color and same texture. The renal column and renal cortex have the same type of connective tissue, renal fascia. Renal column and renal cortex also appear similar in color and texture because the renal column extends medullary to the renal cortex.
