Lightfast Test: Lukas Aquarelle 1862 after nine months

This is the third and final lightfastness test of the Lukas Aquarelle watercolor paints (original post, first update, second update). The reason for ending the test is twofold, the test strip was in the way of a window I wanted to start opening, and after ten full months of Arizona sun the verdict is in. I first hung the test strip in January 2016 in a south facing window. Expecting the paint to be faded out before the first 100℉ (38℃) day.

Lightfast Test: Lukas Aquarelle 1862 after four months

This is one project that seems to slip through the cracks when it comes to doing regular updates (original post, first update). The irony is that the more I forget about it the better the comparison becomes as I leave the test strip in the sun longer. This time it’s been 18 weeks since I first hung the test strip in a south facing window. This weekend is probably the last one of the spring that will see the daytime highs staying under 100℉ (38℃).

Lightfast Test: Lukas Aquarelle 1862 after two months

I originally planned to do more frequent updates on this, but found that there wouldn’t be much to report. It’s been two months since I hung the test strip in a south-facing window. During that time we’ve had one of the hottest Februarys on record. Test strip in window. For a quick review, see the first article in this series. Here’s the side-by-side scan of the two halves. Scan of both halves.

Lightfast Test: Lukas Aquarelle 1862 vs. Arizona Sunlight

Lukas Aquarelle 1862 watercolors are a european brand that is sold in North America by Jerry’s Artarama. Being a low-priced paint, I wondered about the quality of the pigments. So I decided some testing was in order. I bought the following five paints: Alizarin Crimson (1064), Gamboge (1016), Ultramarine Light (1135), Burnt Sienna (1109), and Phthalo Green (1195), in half pans in a Jerry’s store. I have no idea how long they were sitting on the shelf or when they were made.
