A dark roast will visually disguise a lot of defects that can make your cup taste bad. Black beans, beetle damage, pulper damage, etc…take a look at some of these problems (under regular and ultraviolet -UV- lights) that we watch out for, in order to make sure we are buying quality coffee.
It’s important to note some things though: Ultraviolet of Indonesians are available as a unique wet-hulled or dry-hulled (washed) coffees. Giling Basah is the name for the wet-hulling process in Bahasa language, and will have more body and often more of the "character" that More coffee, in particular Wet-hulled process is a hybrid coffee method used in parts of Indonesia, especially Sumatra. It results in a dark, opal-green coffee with little silverskin clinging to it, and a particular low-acid, earthy, heavy body flavor More coffee (which so much Sumatra is) has some caveats. Wet-hulled coffee nearly always looks awful under UV light! You cannot look at it the same way you look at wet-processed coffee.
Also UV light analysis is to gods word on coffee quality – it’s just a clue of potential issues that you would also find in the cup testing, and measuring moisture level and water activity in the coffee.
