So, I can't remember if I posted about this here on Tumblr, but in early July I set out to do a lightfast test for the HIMI Miya jelly gouache. For those unfamiliar with the term, "Lightfastness" refers to a paint's ability (or lack thereof) to stand up to UV rays over time. Some colors fade, some change--as you can see with that purple in the 8th row--and some hold up very well. It's a good way to see if your paintings are going to withstand the test of time.
I wanted to test these paints before I started using them so I could figure out whether it was a good idea to use them in paintings that I want to sell originals of. After this test I will say this--I'll probably only use these on pieces that are destined for digital printing only. Some of the colors are still looking okay, but some (lookin' again at that purple!) are just not up for it.
I was a little surprised that I couldn't find any information on the lightfastness of these paints--hence why I had to perform a test myself. But I hope this serves as a helpful tidbit of information to anyone who had the same questions as I did about these paints. I have yet to use them (mostly because I was waiting on this test) but I'm excited to do so, even taking into account the fading of some of the colors.
GOOD GODS I CANNOT GET OVER HOW MUCH THAT PURPLE CHANGED!!!!!! Look at it!! It’s PINK now! I guess that means that whatever blue pigment they used is not very lightfast. -_-
Anyway, I hope people are still keeping safe and sane.
Please share this if you have artist friends It's weird that this information wasn't available, so if this can help anyone, a quick share is a great way to help people see it. That way someone else won’t have to waste 2 months waiting for the sun to damage their paints :)
