Before now, there was never an accurate way to measure and describe the color range inherent to anodizing. Visual inspection was the only way to implement quality control in the factory, and the beauty of an anodizing job was in the eyes of the beholder. Computerized color control is truly on the forefront of anodizing. The technology is so new that industry standards have not yet been defined for it's use. Most specifiers and designers do not know that the most significant reason for color variation experienced in anodizing is due to variances in the metals used.
Different alloys anodize different colors.
Different lots of the same alloy can anodize different colors because of the tolerances of the alloying constituents. It is likely that anodized sheet you bought from SAF will not have exactly the same color as these range samples because current inventory is a different lot from these samples. Metal supplied at different times will likely be from different coils or extrusion billets and thus different colors. Because extrusions are never made from 5005, these sheet samples can not exactly match the color and texture of extrusions, yours or ours. Note also that these are lab prepared color samples, and actual color will vary in production.
