Changing the color of diesel

crisp1

Here's one for all the chemists out there...
Is there a way to change the color of diesel that will not also change the colour of water (and is preferably fairly harmless)?

Drinking it should turn it yellow.

Thanks but i'm after something a little more helpful than that.

Remembering my LC chemistry, diesel is a hydrocarbon and a non-polar solvent where as water is a polar solvent. It's unlikely that something that easily dissolves in one will easily dissolve in the other. Sugar and salt for example I'm pretty sure won't dissolve in diesel... permanent marker isn't dissolved by water but I imagine it might be by diesel (though I don't know for certain). Anyway... I'm guessing some non-polar solvent based paint or marker might do the trick.

As to it being harmless... in what sense? Pretty sure it's not okay to drink already, despite what another poster "suggested"... also having no water in it it definitely won't turn yellow.

btw I'm not sure on the legality of adding dye to already dyed agricultural diesel... I do know removing it however is illegal.

I've closed this thread, since it seems almost certainly related to illegal activity. Diesel is died different colours based on its purpose and how its taxed.
