Rek'sai's tunnel color on the map

I think those of us that have played rek'sai will know that when you look at her tunnels on the map, that they are very hard to see. And to someone who is mostly colorblind, they are almost indifferent to the fog of war. Perhaps changing the color to somthing that pops out more. like a bright blue, or white circles would really help bring some quality of life changes to her.
