Nike’s color code usually consists of three codes, which refers to the three main colors on the shoes. However, due to changes from research and development to sale, the colors that appear in the color codes do not appear on the shoes. It’s not too different and can be used as a basis for judging authenticity. The following is the color code comparison table for reference. 0 Black1 white2 gray/brown3 green4 navy/blue5 purple6 red7 yellow8 orange9 unknown production place abbreviation comparison table LN - xxxx - Complex engraved, shox basketball, shox training QT - Qingdao - jogging shoes QS - Qingdao - jogging shoes XC - Guangzhou - basic basketball shoes Y3 - Dongguan - advanced basketball shoes and training shoes FC - xxxx - sandals and outdoor leather shoes SF - Shenzhen - football Shoe IR - Indonesian IP - Indonesian IW - Indonesian SF - xxxx - Football PC - Taiwan FT - Taiwan The following is a draft of NIKE's commonly used English abbreviations and their actual meanings SB=SKATEBOARD=Skateboard AP is an Asian shoe board LE refers to LIMITED EDITION (limited edition) ND = New Design (mostly refers to the use of new materials, such as patent leather, mesh...) TB is Team Bulk, which mainly refers to the color matching given to the team to match the team uniform. NU= NEW, mainly new shoes designed by JordanBrand based on the original air jordan sneakers as inspiration when re-engraving sneakers. Nu retro represents this type of shoes. RETRO=replica QS=Quick StrikeCA=City Attack Sp stand for skate professional,- -like Dunk dunk low pro Sp, it means graffit or skate team gei crossover. The relationship between nike dunk / air force one / air jordan 1 is on the same scene. nike dunk is in air force one (1982), air jordan 1 (1985) ), you can see similar design elements appearing on these three pairs of shoes. It is said that the dunk was designed based on the air jordan 1 without the air cushion ( One can’t help but think that AJKO is another product of a similar project.) Since then, it has adopted various material changes and color matching changes as the times have continued to evolve. It is almost certain that it is Nike’s shoe with the most colors. I believe it is difficult to calculate. It is clear that there are several types of dunks that have been released, not to mention that some of the retro colors overlap, so this question can be said to be unsolvable.
