Before farmers could buy paint that would protect the wood on their barn from rotting, they mixed flaxseed oil and milk along with lime and eventually with rust. The combination of this turned the liquid a red colour. When paints became available, farmers continued to paint their barns red in honor of the farmers before.

Not all cows are the colour red. In terms of the question being asked though, it's more down to genetics: Red is the most recessive gene of cattle coat colour, and is only able to come about if a red bull is bred to a red cow. The only exception to this is the incomplete dominance gene in Shorthorns: if a roan Shorthorn bull was bred to a roan Shorthorn cow, there would be a 25% chance that they would get a red Shorthorn calf.

There are several breeds that are red in colour:

  • Hereford
  • Red Angus
  • Red Shorthorn
  • South Devon
  • Devon
  • Red Poll
