Color blind setting for Nav?
 

I'm mildly color blind (I see colors, but some look the same to me). Specifically, I can't tell the difference between the shades of yellow and green used to indicate traffic on the Nissan nav. I've tried various mixes of day/ night and adjusting the contrast and brightness... but no dice - "some traffic" and "no traffic" look the same.

Dug through the manual and searched these boards and haven't found any reference to any sort of color blind mode, so I'm assuming I'm just going to have to deal with it. If I'm assuming wrong, please let me know.

Thanks!
