Yellow lines on the Wanderkarte Schweiz indicate 'Wanderweg' = walking path. Red lines indicate 'Bergwanderweg' = mountain walking path. Bergwanderweg are officially more difficult than Wanderweg, so for example you can generally get away with trainers or even sandals on Wanderweg, but for Bergwanderweg you should wear proper walking shoes or boots.
On the ground, Wanderweg are marked by the famous yellow signs, Bergwanderweg have an additional red and white stripe to indicate the increased difficulty.
There is a third colour - blue that indicates 'Alpinwanderweg' these are climbers paths through the most difficult terrain.
