Hi Johannes, Thank you for doing this - I look forward to seeing the results.
Colour vision is one of my interests, as I have a lot of trouble with distinguishing colours, and I have been meaning to make a service to filter map tiles through a colour vision simulation...but I have never got around to it - have been carrying the research papers up and down the country for the last 6 months, but haven't done anything with them.... I did produce a FM-100 simulation in java a while back, but yours is much better! I don't know if I missed this subtlety in your examples because of my colour vision problems, but I would have been more inclined to vary the thickness of the casing around the road - it is quite a good indicator of its 'importance', and you can make roads look different without using up more colours - you could stick to nice bold colours (pastel colours are nasty - all look the same!). It is clear from your tests that you have realised that thicker is much easier than thin, but of course the map does not look so nice that way. Regards Graham. -- Graham Jones Hartlepool, UK.
