    On first appearance it does seem to be a good idea, but then some airports are extremely complicated with taxiways all over the place and lots of crossing taxiways. You would have a lot of crossing colours.

    As someone has mentionned already, some airport have 'follow the greens' where at night ATC light up the green centerline lights specific for each aircraft. Assuming ATC do not get it wrong, this system is great, but only works at night.

    As the coloured taxiways would not change colour, you would be told to "taxi on the yellow until you get to the blue bit and follow that until the orange bit then left again onto the green bit and on the red bit for bay 6" Given an instruction like this, it is no real easier than being told "A1, B, G, E4 for bay 6". If pilots are getting confused with all the taxiway letters and going the wrong way, there is no reason they would not get confused with so many colours either. Not the mention the cost and how at night in the rain, or day in the snow it would all look the same anyway.

    The future is moving taxiway maps on your Electronic Flight Bag showing where your aircraft is and your taximap marked out, or arrows on your HUD for those aircraft that have them.

    Most dangerous accidents and incidents on the ground are runway incursion events and the colour idea could be useful if runways were a different colour to all taxiways, but having lots of different colours all over the place is not really the way.

      To add to what Colin said, prehaps it would be easier if airports made the taxiways and runways different surfaces. Even in VFR conditions, it can be difficult sometimes to distinguish runways from taxiways if they are all appearing to be of similar lenghts and colors. If runways are asphalt, which is rather dark, and taxiways are concrete, which is consideribly lighter in color, then it may be easier to distinguish the two.

        If anything, it may stop people from landing on the taxiway which we hear about from time to time.

          That is another one of the suggestions that my paper makes. We were thinking of using whitetopping for the runways, which a bright white.

            If the runways are all white, it makes the runway markings blend in (even when outlined). How about all black runways and neutral grey taxiways?

              Well there would be some changes in pavement markings... the big deal about whitetopping is the simple fact that it is simply paved over the current runway, it lasts up to 3 times longer than conventional concrete, and the maintenance cost is about 1/5th of normal concrete.

                A solid white runway would be horrible on a bright sunny day. Everyone would need mega sunglasses!!...not to mention the majority of aircraft these days have a white fuselage so on finals you would not be able to very easily see if there was an aircraft already lined up...when it comes to runway incursions this could make things even worse.
