"In the graph, you can see lines of different colors: BLACK shows the moving BS412 output level and should be below, but as close as possible to, the 0 dB line. RED shows slow volume changes. In general, it's best if this line doesn't drop below -1 dB - bigger drops can be noticeable. GREEN/PINK shows short-term volume drops caused by the compressor. YELLOW spikes show that the de-esser reduced loud highs. The actual drop of the highs is less than what is depicted here. BROWN spikes show the de-basser in action."
where's the description for white and light-grey?
