Gray, Green , Pink and Perchlorate

[displayfireworks1]

This is a test for perchlorate in three different colored fuse. To refresh your memory from the quick match test. The methylene blue will turn purple and not properly mix in cold water that contains perchlorate. Here are pictures from the test.
Is this an expected finding or not?

Kinda what i would expect... Especially with the pink and grey fuse.... Perchlorate is a stronger oxidizer than nitrate... I heard about a perchlorate based lift powder the other day, sounded like flash with charcoal instead of metal...
