Actually I've dyed materials with the residue of boiled and simmered red onion skins. I got red not yellow. Yellow onion skins yield yellow.
Searching for an equivalent to picric without the potential for pyrotechnics, I stumbled across a decent golden olive:
partridge
hen pheasant
grizzly hen
2 packs Pineapple Kool Aid (only place I've found this is in Phoenix; seems to be a Southwestern thing)
1 pack Lemon Lime Kool Aid
2 drops yellow food coloring
1 drop red food coloring

Scott,
You need to clean out your PM box, I can't get to you there!

Picric acid, huh. When I was a grad student and the Head TA, we had a really obnoxious colleague, just a real PIA. So....... before his lab section we went and put a very, very thin layer on most of the surfaces he would touch first. Lots of little pops and bangs and the roars of us laughing. No harm to them, but they never, never tried to mess with the rest of us again. Now, I would probably be suspended and arrested! Then, a harmless prank to teach them a lesson.

Started out with the kool-aid, easter egg dye, then RIT and tried the Veniards but got tired of every time I went to order from a shop in NH they were out of the color I wanted - they only order twice a year. I've been getting Fly Dye from Anglers Workshop, if you can measure 1/2 tsp of the powder, boil a quart of water and mix them together then white vinagar to set the color anyone can do it. I believe there dye comes from Orco but still checking on that.
The last three dyes I got from Anglers were Blue Dunn, Slate Dunn and Olive
This is the Olive from Anglers Workshop
Blue Dunn
Slate Dunn on mallard flank and on arctic fox
Ginger was the goal today (turmeric supposedly an option to Koolaid/Rit but we only have a little in the spice rack). A little Rit golden yellow and a drop of black - looked like greenish something in the dye bath but yielded a nice ginger/cinnamon.
This was pretty much undiluted; a bit more water would lighten things up a bit.

Scott
