The angle of reflectance is a critical component in gloss and color evaluation. In all cases where color matching is important, it's critical to specify the rules for evaluation, including angle of viewing and the light source to be used. You can find some good information on this subject by Googling for "gloss vs. color" (without the quotes).gpainter said:How much does gloss affect the appearance of color? I was told that a 10 gloss unit difference may make the color match appear different(lighter/darker, even if the color matches) to the Customer's eye. Any color/gloss experts?
Adriane said:In my limited experience, the higher the gloss (the smoother the surface) the darker the color. A sample with a higher gloss would appear darker than an identically colored sample at a lower gloss.
As was said before, the angle of observation does play into the exact measurement of gloss. A good spectrophotometer allows you to view from a variety of angles. But to the naked eye the above is a general rule.

We have used the gloss meter from BYK Gardner and are thinking about using their spectrophotomer to do comparative tests. How does their tools compare to others?
