Any tips/leads on colouring e-liquids?

[stayinwonderland]

What kinds of colours can go into e-liquids and where does one get them from?

I saw a vendor recently, can't remember who, that said they use non toxic colours at a 0.01% mix or something along those lines.

Doing some DIY and might want to experiment with having this as an option.

Just don't do it is my advice. Id rather have eliquids without colours in personally!

Agreed. You really don't want to put anything into your lungs that you really don't need to. All the flavours we use are selected because they have ingredients that are considered safe for inhalation and even then it is better to use the least amount you can to get away wih to get the taste you need. Colour, whilst looking awesome in tanks, has no benefit to the vaping experience
