I was hoping to avoid having to bother you about this, it's a relatively minor issue, and I have my own workaround, but I am having problems getting any of the vector renderers to do anything beyond the normal color scheme. Using OSM maps, the back roads I'm often on are white, as is the background of the screen, making it difficult to see the road I'm on. The built in renderers all produce the same output. I've downloaded some .xml files from an OSMand discussion that are high-viz, but they too produce the same results.
Any ideas? For now, I'm using night mode, and I think that'll work fine, but I'd love to be able to tweak colors to exactly what I want.
