Abstract: New methods of producing anodized aluminum alloy products having an improved surface appearance properties are disclosed. The methods may include preparing an aluminum alloy body for anodizing, thereby producing an anodized aluminum alloy body, contacting an intended viewing surface of the anodized aluminum alloy body with an acid, thereby producing a prepared intended viewing surface of the anodized aluminum alloy body, and sealing the prepared intended viewing surface of the anodized aluminum alloy body. The anodized aluminum alloy products may realize a preselected color tolerance, such as realizing a b* value that is within a specified tolerance of a preselected b* value.
