If you want the best, most consistent brass for competition or LR precision shooting, just invest in a top tier annealer. My choice - Bench Source.
I have tried the manual and simplier methods. Results were irratic and inconsistent. So, I created as many problems as I tried to resolve.
With the BS annealer, I can control flame (location and heat) and dwell very precisely. I have found this is necessary for best results.
Colour does not work... use a temp indicator like Tempilac. Some brass turn that beautiful colours, some don't show any visible change.
Different brands and lots of brass will react and look differently and need different treat schedules.
Also, number of times you fire a batch of brass before you anneal WILL affect the appropriate schedule. Just keep things consistent.
The goal is not to make exactly like factory (maybe you can). It is to make it consistent from firing to firing.
Unfortunately, annealing IS very complicated and demands the right tools to do it well. Most brass manf will show you every part of their manf EXCEPT their annealing process.... Why?
YMMV.
