To sell that, you'd have to spill marinara over the entire table.
I've got a pair of jeans that I spilled a good portion of a cappuccino on 'cause it was in a paper cup instead of my porcelain (we were shooting for ESPN on the UofA campus on both sides of Cafe Luce, so I had to get one on the way to the next location. I had to!) that are at the laundry as we speak. If the capp stain doesn't come out, I'm gonna dye 'em with a cappuccino stain pattern.

Alright, gang, as promised, I've done the coffee dyeing experiment!
The photo essay is available on my Flickr Photoset: Dyeing Coffee Rags, or you can read on for further narrative accompanying the photos.
I started out with about 3 days of coffee pucks. I've been consuming more coffee than usual (4-5 doubles/day) as a result of the mystique of getting a new grinder, so this is a good bit. My Bumper knockbox was nearly full. In addition to that, I purged the remaining coffee from my grinder, which was a little less than a double shot's worth of coffee.
To speed things up, I started out with water from Vetrano:
Fresh grinds + Boiling Vetrano water, awaiting the addition of the pucks (lower right).
I gathered my rags; I planned to do four of them, in various states of usage as you can see below:
I loaded up the rags into the pot...
... drove them down ...
... and away I went to boil them.
I wanted to boil them for an hour, but I ended up having to settle for just 45 minutes, as we had to go out. After the 45 minute boil, I turned off the heat and left them to sit for about 2 hours while we were gone.
Upon my return, I was greeted with a sludgy mess of rags.
Cleaning them off was a real pain in my sink, and I would strongly suggest doing this outside in a garden with a hose, if you have the means. If you must do it indoors, as Chris said, make sure you have a way to filter the grinds to prevent the lion's share of them from clogging your U-trap. It's a LOT of coffee grinds to go down at once.
What a mess!
After wringing out as much of the coffee as possible, I put the rags in some ice water. I guess I was thinking that the hot/cold contrast would help set the color best:
After the icing, I wrung them out some more, and then boiled them again, this time in plain water, for several minutes. One more bout in the ice, and more wringing:
... and I was ready to wash them. I put them in the washer twice, first on cold, and then on hot, and then dried them. The results:
The control rag. This is one of the used rags that I didn't dye, for some comparison. Note it's stained and not perfectly white.
This is the one dyed rag whose stains didn't get covered. This particular rag was used to wipe out some burnt coffee oils from inside the grouphead to expedite the backflushing process (and get some stuff it just can't get). You can see these stains are much darker.
Finally, one of the rags that came out quite nicely. The other 3 looked like this.
As you can see, they are fairly light when dry. The pictures above make them look a lot paler than they look in person, but you get the idea. Wet, they look almost as mocha-dark as the above image of the rag before washing, but after a thorough wringing out.
Here you can see the rags under my sink, where I keep them:
The bottom rag is undyed... you can see the contrast a little better here.
And here's a parting shot of a damp rag on my countertop next to my setup:
Somewhat darker when wet.
I enjoyed the process, and I think I would do it again. If I were doing it again, I would change the following:

- Bigger pot + more water. There's a lot less work involved if you have enough water for the rags to get swished around on their own in the rolling boil of the pot.
- As I mentioned before--Rinse off the rags out of doors. It's a pain to keep the coffee grounds from clogging your sink--there's a ton of them!
- Use less coffee. Judging by how this run went, I think I super-saturated the water. I think it would have been equally effective with half the coffee (or twice the rags).

I wonder if non-used coffee would help to get a darker stain... Hmm...
Luckily I have a ton of bad/old coffee, and nothing to use them on. Sadly my rags don't need any dyeing yet since all the nasty stains they pick up comes out nicely in the washer... I might on the other hand get some white rags (I should probably see if the cabinets in my house contain any such loot first) just to satisfy my curiosity.
And finally one could probably use some sort of a natural stain that gives a darker brown color, onions maybe?

I have seen red, green, yellow, and white onions. Never a brown one... Are you talking about carmelized onion? I don't think it could come close to the brown-staining power of coffee.
Fresher coffee is bound to work better, but I don't think it's going to matter all that much. If you want a darker brown, I would bet you're going to have to either do more iterations (I will try this next week), or get a normal brown dye. I am sure such a thing is available, and, if you spend the money, as natural as coffee grounds.
I am not sure how much darker is needed. At some point, you'll have trouble telling when they get dirty!

After reading this thread I conclude that caffeine must stimulate ingenuity. Why not dye one's favorite towels in one's favorite beverage?! It did tweak some old memories, so I checked the web for natural dyes and found a material and method for dark brown that Stuggi asked about, and making the color fast (mordanting with alum) at:

shadowfax, great work
I am "dyeing" to know how this all works out

Why not just soak them in brewed coffee? That would be similar to the tea dying which works well.

That would probably work, especially undrinkable, super-saturated coffee steeped much longer than normal.
I think tea stains a lot better naturally on account of its tannic (?) acid. Certainly, it stains cups horribly compared to coffee.

Why not just buy & use black face cloths so you never have to worry about the coffee stains?

Ok so buy tan ones or tan hand towels. It beats boiling white ones in old coffee grounds.
