Hi guys! I did a test to see if markers on fur will fade and it was requested that I share it so here it is!
I used Prisma markers on some low quality white fur. The piece on the left was put on the windowsill in direct sunlight, the middle piece was in normal room light (on the back of my sofa) and the right-hand piece was put in a drawer so had no light. I then left them about 6-8 months.
As you can see, the one in direct sunlight faded, while the one in normal room light doesn't show much difference to the one kept in the dark. So the verdict is that as long as it's stored out of strong/direct sunlight, there isn't too much of a problem with fading.
Results of the faded direct light piece-
The colours most affected is the light violet and orange, having faded almost completely away.
The colours that faded considerably were the bronze/ tan (light browns) peach and yellows. The peach also went a more redder colour before it faded.
Ones which faded and went more grey in their appearance were the purple, red and dark green
The least affected was the black, warm/cold/french greys, the blues and the mid green colours.
Sorry if this is big, I can't find how to do a Lcut *fail*
