Isn't lemon juice a mordant in this case?

green and I donn't think it was dyed- or is this a sure sign?
: From what I know of using natural dyes (and it is very little) you
: will need to use a mordant on the fabric to get better adhesion of
: the dye. Also henna adheres to proteins better than cellulose in
: cotton so you would have to find cloth made of wool or silk rather
: then cotton. The green could be the chlorophyll of the henna plant
: or more likely it is the green dye that the henna suppliers add to
: the henna powder to make it appear fresher.
