ASC tube trap full round with dark and light sides - diffusing vs absorbing


In the older model full round ASC tube traps, one half is light coloured and the other half is dark charcoal coloured. Does anyone know what the colours represent? Which of the two colours is for diffusing? Thanks.

At a distance of about six inches, speak into the tube trap.  Turn it 90 degrees and do it again.  The absorptive side will seemingly swallow your voice.
