Lightfastness Tests

Though I don’t always remember to do it, I like to put swatches of all my art supplies up in my window for at least six months to conduct my own lightfastness tests. Obviously these aren’t as scientific as tests conducted by the manufacturers or even those discussed on the Handprint website, but I do feel like they are a good indicator of whether a particular colour will stand the test of time. Under each chart is a link to my review of that product.

Starting in 2014 and running until 2015, I conducted lightfastness tests on all the watercolours from all the brands I owned at the time. After scanning the charts before exposure to sunlight, I scanned them again at 1 month, 4 months, 8 months and 12 months. You can read about those tests here, or just view the 12 month charts below.
