Green is the original TOA system... in several versions.
Green was definitely NOT a "plug and play" system. The pioneer
Green systems paved the way for all of us in this 'hobby'.
Green generally only detects "C-G' strokes.... We owe them all a debt of gratitude for their hard work, the experience and knowledge acquired that they have provided, and for their loyalty and perseverance.
Red is a more advanced system, and still requires owner construction and optimization, and in its '
basic' configuration only detects "C-G" strokes.
Red is the core of the upcoming "
Blue".
Red offers more advanced filtering, simpler settings, better quality, and more data, especially with the addition of E field capability. This allows the potential (as it becomes active on server and local firmware,
for those with E field implementation) for stroke polarization, type, and much better stroke location and detection.
Red also implements more advanced
TOA and
TOGA algorithms after server processing, many yet to be implemented.
Some
Red operators who have NOT optimized their systems, or updated with correct antenna info since installing, e.g., may have a rude awakening when all the new server requirements are implemented... possibly very soon. Later this year, the Green station data will become incompatible, and Green operators should watch BT website for info and possible special consideration.
Reds will be thoroughly compatible.
Blue implements all the experience, acquired knowledge, and capability of
Green and
Red systems.
Blue will also implement many suggestions and ideas from both
Red and
Green operators.
Blue will likely be available in several forms - from a basic 'assembled in a housing' (sort of 'plug'n'play) basic system, to kits of varying 'complexity' of construction requirements and included parts, such as antennas. Antennas and E Probes will become standardized, either physically or electronically.
Blue may have color 'touchscreen' display as either standard or optional.... that's still under discussion.
Blue may have a slightly wider bandwidth, simplified E field, and the potential for 'vertical' H field detection in addition to the standard 'horizontal' H field.
Blue will, as current development would seem to indicate, also allow -
for advanced operators - more specialized filtering and filter circuit insertion. There will likely be some level of "self test" features.
Blue will take many of the principles learned from
Red, such as Preamps for antennas/probes to a single amplifier board, for all channels. Better and more advanced 'on board' power supply regulation and filtering... dual or even triple rails, for e.g.
Now, to answer your most important question...What is the 'system naming' convention?With the exception of the 'Discovery Modules"...
simply from the color of the circuit boards as manufactured....
Green,
Red, or
Blue 
Cheers!
