he original artwork problems:
1/ Has too many color, Please restrict to use 4 different strike colours with Black Ground color
2/ the artwork will be print on fabric, so the tiny colour segment is too narrow which cannot be printed clearly on fabric. So the re-created artwork need to have bigger segments. Understood it will unavoidably to simplify the detailing.
3/ with above requirement, please try to keep the marble-like pattern. It's okay to look 60-70% similar to the original
4/ The re-created AI file can allow me to change each of 4 colors easily
5/ the stripe should be left-right, top-bottom repeatable.
For the coloring,
1/ BLACK (ground color)
2/ Light Blue (strike color)
3/ Light Purple (strike color)
4/ Light Green (strike color)
5/ White (strike Color)
