Cool 
I understand that the need is for visitors and potential hub to clearly understand what the actors on the map represent.
I also undestand the confusion with current red / green / white colors.
I guess there could be various solution to improve visitor readability:
- add a legend would be one
- make all icons green is another one
- make all icons white (neutral)
- choose other colors than green and red but that enable to distinguish suppliers from actual sellers would be another one. Like yellow, blue and white.
I feel a little bit annoyed still by the fact that on shop page icons appear in red. Isn’t there a discrepency ? In the case the “make all icons white” would be the less confusing…
This is connected more broadly to discussion on how we evolve the directory.Making OFN an open directory for all the local/sustainable food ecosystem and [WIP] Revamping OFN as Enterprise Search & Directory and WIP : Improve OFN Map / directory but those are broader project and we can start with a first level of answer to the need.
