What is the cause of grey nonspecific colouration with a pinkish hue in silver staining?

In silver staining, the final color of the image is shaped by the toning step with gold chloride after development. Toning modifies the deposited metal and stabilizes the stain, and the amount of toning determines the hue. If toning is taken too far, the image becomes over-toned, and the color shifts toward a grey with a pinkish cast because excessive gold deposition changes the light reflectance of the silver image. This pink-tinged grey is a hallmark of overtoning with gold chloride. If toning weren’t enough, you’d see a weaker, less distinct color from under-toning, and other issues like residues from insufficient washing can cause background haze, while excessive light exposure tends to fade or alter the stain rather than producing the specific pinkish grey hue.
