Overall approach looks good IMO.
Though I'd like the lower colour extent a bit further up (green lined area in image):
EDIT:
I think splitting the edge lines/conds is a good idea. Lines take their colour from the base colour of their file; so if s01 is dark grey, s02 trans-orange it might loook odd (trans-orange area getting solid colour edges).
