Last years, I read on the web some artists been using coffee for painting. I decided to experiment it myself. First, I made myself a supper strong coffee, I used double amount grounded Starbucks coffee to make one cup of coffee. Once the coffee was cool I try to use it as how I paint in watercolor but the color was too light. I left the coffee overnight hoping it will make the color more intense. The next day when I used this day old coffee it has the intensity I wanted and I painted an orchid painting which turned out well.
However, I don’t see any advantage of this coffee paint than using watercolor or ink and with the price of the coffee it actually cost more so unless I at a situation I don’t have my watercolor with me and I would not try this again.
