The dyeing is preferably done immediately after anodizing process. The anodized components should be thoroughly washed free for all residues of the anodizing solution and stored in cold water. Coloring with inorganic coloring matters is affected by precipitating a colored compound in the pores of the film. It this process, the anodized parts are immersed first in a solution of one compound. In both solutions, the parts are kept for 5-10 minutes. The solution are used at room temperature. The component of some suitable solutions of this type are given in the table.

| Green Yellow | Sodium hyposulphyte (10 - 50) | Potassium Permanganat (10 - 50) | Manganese sesquioxide |
| White | Barium Acetate (10 - 50) | Sodium sulfate (10 - 50) | Barium Sulfate |
| Orange | Potassium Chromate (10 - 50) | Silver Nitrate (50 - 100) | Silver Chromate |
