Assigning random colors to Pflow
Is it possible to assign colors per particle without Box #2/3?
I am currently working on a project where the goal is to display light reflections over the course of a year. Where the reflected light intersects the target, I would like to place my particle (I have that script) and color/material it based on the month it happens in.

Yes, you can use a Script Operator and the function
setParticleMapping < index >particleIndex < int >mapChannel < point3 >mapValue
with mapChannel set to 0 to affect the Vertex Color channel.
Then add a Material with Vertex Color Map in the Diffuse slot to the PFlow and you are ready to go!
For example, set up a PFlow with Speed set to Random 3D and values 100.0 and variation 100.0. Then add a Script Operator and put this in it:
Add a Material Static, drop a Standard material, assign Vertex Color Map to Diffuse channel and render in Scanline - fast particles will be green, slow particles will be red...
