S5 Quattro Coupe (8T3) V8-4.2L (CAUA) (2011)
A permissible range of white for the road traffic is defined by law (Figure 1, Area 1 within blue dotted line).
The LED manufacturer sorts the complete production volume according to even smaller color ranges (Figure 1, Area 2 in black grid).
To get the fewest possible color deviations, Audi uses only part of the manufacturer's already limited range and thus only a small section of what is
legally permissible for road traffic (Figure 1, Area 3).
In production, a finer color selection is not possible; this can lead to minimal color differences. This is normal.
