The depth of the dye tone is determined by the time of immersion
both in the copper toning bath and in the dye-bath. Pale tones may
therefore be obtained either by giving a short bath in Tone A and
fully dyeing, or by toning for a longer time and giving a short
immersion in the dye-bath.
By mixing the dye-baths J, K, and L in varying proportions
intermediate colors may be obtained just as in tinting.
