What is it that you are wondering about?
This is Peter’s explanation of them:
“The most common cell is called “Swoop”, which is so named because it creates a simple up-down gesture, with pulses to mark its middle and endpoints. It is triggered by pulses (at their * node) and also create pulses (at their + node). Each puts out a triangle after triggering at the * node, and each receives a control voltage at the + node. So you see, each of the two nodes is both input and output, dealing with pulse as well as DC voltages. The condensing of nodes is important to make (re)patching the multiplicity into an intuitive affair, and it emphasizes a strong Yin-Yang nature. To compliment the Swoop, there is an Antiswoop, which is a simple inversion of its gesture. Swoops and Antiswoops can be chained together in any combination, looped, woven, and triggered by Preamps or Antipreamps.”
Rando and Anti-Rando are essentially a Swoop with a couple small changes -
Behavior being, the Rando likes to randomly generate sloped pulses, much like the Swoop, but will sometimes throw an extra undulation or ripple in there - 
Hopefully that helps!!
For your color-coding - excellent! - I went with purple and green for and green and grey for randos and swoops - but that was entirely personal pref.
Technically one of the nodes in swoop is the actual out - but because they can be chained - they are still androgynous, so you can very well utilize browns
