A lab slide dye could be eosin.
It will try to slide out of it, but it will dye after a while.
methane blue
Take it to any photo lab and have them print it.
Yes, if is wasn't it would mess with the lab.

Yes, you can use food coloring to dye specimens for a microscope slide. However, food coloring is not as effective or long-lasting as specialized dyes used in laboratories. It may also interfere with the clarity of the specimen when viewed under a microscope.
Because some things that you might look at under a microscope are transparent and hard to see. Adding Methylene Blue to the slide would dye the stuff blue.....i think.
Methylene blue is a synthetic dye that binds to specific cellular components in the lab setting. Wool, on the other hand, is a natural protein fiber with different chemical composition that is not compatible with the dye molecules in methylene blue. This makes it difficult for the dye to bind and penetrate the wool fibers to result in staining.
I accidentally spilled a drop of coffee on my shirt.
Clothes get their color through the dyeing process where fabric is treated with dye to impart a specific color. Dyes can be natural (from plants or insects) or synthetic (created in a lab). The color molecules in the dye bind with the fibers of the fabric, giving it the desired color.
The colored chemicals that you mix into a stink bomb are in the Science Lab at the school. (Mix blue and yellow and heat it.) (see related question)
