The term "lizard" pattern has been applied over time to mean the horizonally-striped French patterns of the 1950s that were direct descendants of the original British brushstroke pattern of the Second World War. The French generally referred to the pattern as camouflee de leópard (leopard camouflage); the term "lizard" actually refers to a local nickname for French paratroops during the Algerian War. As paratroops were synonymous with the striped camouflage design, the nickname stuck and over time came to refer to the camouflage pattern itself. This term has interestingly become the most widely accepted name among historians and collectors for the original French design, and the innumerable derivative patterns that were spawned thereafter.
There are generally two types of lizard patterns, those with horizontal orientation and those with vertical orientation. The original French "lizard" patterns were horizontal, but those developed by Portugal shortly thereafter were vertical yet in other respects influenced by the same design. We therefore categorize both vertical and horizontal designs as "lizard," as both styles have their tributary designs which have continued to be produced today.
Tiger stripe pattern camouflage is derived from the "lizard" design, and is essentially the same type of camouflage, but of a more consistent strain.
