Points forming a chain which leads to destination for treatment, and also points to harmonize, are marked by green as general rule, however recent probes on diabetes 1 type case have shown marking all points for Spiral/Triorigin schemes in black, works well. This may somehow correlate to the nature of a disease. i.e. Neito - total loss of function due to destruction. It may happen this will also work well for other autoimmune diseases and Neito conditions.
This also makes patient more sedated which may help restore energy during a session. There seems however, that it's best to have this symmetrical i.e. mark points in black for both hands or have it
in one scheme on central line, like on abdomen with centre in navel, as having this on only one hand gives sense of imbalance.
