1) Upload PNG Segments (multiple, layered in order)
Tip: the order you select files = layer order (first is bottom).
2) Upload Filename-with-Colors (parsed only, multiple)
Example filename: ffcc00-112233-00ffaa.png (3- or 6-digit hex per segment)
Parsed colors (set 0/0):
(no set)
(none)
If multiple color-sets are loaded, this will download one file per set (your browser may ask to allow multiple downloads).
