Usually the color of low-density magnetic strips is brown, and the color of high-density magnetic strips is black, so that users (including card manufacturers and issuers) can distinguish low-density and high-density magnetic strips in color during production and storage.

7. Color gradation: The ideal range is 18%-85%. If the highlight part is lower than 18% or the dark part is higher than 85%, the color gradient will be poor.
