Answered question
From an accessibility standpoint, there's not enough contrast between the grey "no coverage" areas and the very light green coverage areas (outside of the subscription area). I have a hard enough time seeing it and have 20/20 vision... Someone who is colour blind or with reduced vision would probably be unable to see the difference.
Comparing Fizz's map to another carrier like Virgin, there's a huge difference. Nobody would have difficulty with Virgin's map.
I couldn't agree more! It is very difficult to see the different coverage zones by color! I am slightly colorblind but can still barely make out the color differences. Barely. Please change the colors Fizz!

Agree... not just for people with reduced vision... on crappy LCD panels it is a challenge too.
