Black to purple, greenish.. etc

[Gerbil Jammer]

Has anyone left their test drop ( I do mine on a white plate so I can notice any and all subtle changes) for about 5 - 10 minutes and notce that the color IS NOT actually black, BUT either DARK DARK GREEN or Purple? I HAVE NEVER gotten black. It's always a dark base color. You would think it wouled be black, but if you take a fork, knife or whatever and run it through the drop to make "trails" or a weird design, you'll see that it's actuall green, etc..

Mine seem to show a green rim to them after they sit for a long time (sometimes I put the plate in the sink and don't rinse it for an hour or so).

When leaving it for a while in open air, you may get all sorts of (dark) colors.
However, this does not reveal anything about the substance.
You only need to watch the first 5-30 seconds.
The colorchange after 5-10 mins. orso could be influenced by many things in the testing area.
Smoke, air and anything that flies around in your room.
Don't bother about it, it is of no importance.
