Methods of and systems for automated color control are provided. These methods and systems are suitable for use in various oxidation processes for the coloration of heat treated steel, for example razor blade steel. A feedback loop (closed loop control) is established, including the steps of measuring color, comparing the measured color to a target color and quantifying the difference there-between, and, if the difference exceeds a predetermined threshold, adjusting a color adjustment parameter, e.g., the airflow to the oxidation zone, so that the measured and target colors are equivalent or within a predetermined variance.
