If I had to guess, it’s mostly water.

The really scary stuff (in aqueous solutions, anyways) isn’t usually brightly colored, it’s usually clear. Of course there are exceptions - like bromine or iodine - but I know what those look like and nothing on that tree looks like either of those.

The reason for that is that most pigments are conjugated ring systems - complex organic molecules that break down in harsh environments - so anything sufficiently reactive would actually destroy any colorants you added to them.

I’m not saying that bright, friendly colors are always safe… but the easiest way to get a bunch of bright colors is to use food coloring and water.

Thanks for the good work! Education is important!

I couldn’t express it better myself. Although in terms of “having a functioning democracy” the colonizer countries aren’t exactly doing well either. (It’s almost like powerful people will exploit anyone and corrupt any system…)

I’m sure their democracy functions about like everyone else’s - i.e. not democratic at all
