The patterns are editable and you can import them into 2D CAD or vector software, change and color them, i.e., do with them anything that is needed for your project. Illustrations like these are not difficult to draw if you have a 2D CAD or vector program, although the drawing of the jaguar/leopard is time-consuming since there is a large number of spots each of which needs to be traced manually. In vector software, there is an option for automatic tracing of illustrations, which is only suitable for graphic projects and this is why we do not use it in our work - we try to make our vector patterns suitable for craft techniques and CNC machines as well.
The story about big cats is interesting and unusual. Panthera is a genus within the Felidae (cat) family which includes the lion, tiger, jaguar, leopard and snow leopard, i.e. all five living big cats above may be considered panthers. Normally, the big cats’ coat is yellow or yellow with black stripes or spots, depending on the species. However, jaguars and leopards sometimes exhibit a genetic mutation called melanism (caused by excess black pigment melanin) which results in their coat to be black. These black individuals of both jaguars and leopards are called black panthers. Normally colored yellow-and-black kittens can be litter-mates with the black ones, regardless of the color of their mother. Melanistic individuals, or black panthers, are more common in regions of dense forest where light levels are lower, suggesting that melanism is a selective advantage for better camouflage.
