On the Internet, I found two geeks thinking about the details of these sneakers. They concluded that the sneakers were brown.But, Deckard's shoes had brown laces?
But I went further. Listening to the book "Do Androids Think About Electric Sheep?" I came to the conclusion that the atmosphere on earth was very corrosive in the truest sense of the word. Constant acid rain negatively affected the quality of materials.
Conclusion: the color of the laces is "corroded black".
Today I will show a photo of how I can make this color.
