Modifying Google maps?

[BritishInvader]

Is there any way (or are there any apps available) to change the ways the Google satnav works? I find when I'm on a motorway the road is purple and the route I need is in blue and as my eyesight isn't the best it makes it a little difficult to keep tabs on where I'm going so if there was a way to change the colour scheme I'd be grateful if someone could show me how

I do not know of anything to do this, but that would be awesome. I think Google should consider adding this so that we can change the route color. Sometimes it is difficult to see, I agree. (especially when driving near a river or on a highway along water).
