Hi Johannes,<div>Thank you for doing this - I look forward to seeing the results. </div><div><br></div><div>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!</div>
<div><br></div><div>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!). </div>
<div>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.</div><div><br></div><div>Regards</div><div><br></div><div>Graham.</div><div>
