Here we have some new road-colours - and not more this "not to see"-green for the trunk-roads, if the road is between green landscape. Is this new "#ff69be" (in the colour-table named as "hot pink") too much hot? May be we can make it a little bit lesser dominant. Primary now is "#ffa501" and secondary "ffff01", which means nearly plain yellow. The colour of motorways (blue') and tertiary and lesser roads and pathes are unchanged.
Sure there is some smoothing-work to do (the ref-shields and some pieces over bridges).
The garden-pattern has now colour #77e72f as iiEarth has suggested.
Next step will be a seperate colour for freight-railways. We already have blue for subways, green for commuter-rails, red for hi-speed trains. Can we drop the green for the commuters and use it for freight-rails or did you think, we need a seperate colour for both? And if yes, which?
