I’m excited that you are doing a lightfast test! I would love an update on how they change over time and exposure. I love watercolors and it would be cool to try this If they don’t fade too much. Thanks for the video!
I hope it goes well! To your other question: the Color’s do not rewet well (the blueberry does somewhat but raspberry and strawberry barely) I covered the paints with plastic wrap to keep them wet and used them up over the course of a few days. It’s definitely best to make what you need each time :)
Is there a reason why you just use gum arabic? I am looking into making my own watercolors and saw some recipes with use of honey and/or glycerine to it.
