Changing Color from "Wanderroutes" and possibility to get a clean map

Hi, I am new with Locus Map. I got confused with the amount und color of the different "Wanderoutes" for example HW 10 Rhein-Main-Weg, O5 Ortsrundwanderweg, Rundwanderweg Gross Bieberau and so on. Is it possible to inaktivate them? If I zoom in Windows Web App and Android closer additional the color of this routes change. Can I get a "clean" map or a field where I can select them e.g. only Way E2? Thanks for your help,
