_______ determines colour, texture, chemical properties, mineral content and permeability of soil.
Parent rock
Soil forms from weathering of the underlying rock. The parent rock supplies the original mineral grains, and through that determines the soil's colour (mineral pigments such as iron oxides), texture (particle size from rock breakdown), chemical properties, mineral content, and permeability (linked to texture).
Climate, time, and flora & fauna modify the soil afterwards but do not originate these intrinsic properties.
