Unclassified roads and tracks both are drawn with very pale colors, almost white. This makes it very difficult to see them against the aerial photography when drawing in an area with pale soil or covered with snow. Some kind of color would make drawing much easier.
I'm also not wild about the new rendering colors. I prefer red for primary roads, orange for secondary and yellow for tertiary. That color scheme made sense. The current one is odd and often makes it difficult to tell the difference between roads.
