This winter I decided to test the lightfastness of many of my inks and a few pencils. I thought I’d lost the test sheet but it turns out I had stuck it to a different window when I had checked it. The results are interesting.
Not lightfast, showing large color shifting or significant fading:
- Chelpark Turquoise
- Camlin Royal blue
- Pilot G2 blue
- Sharpie Ultra Fine Point Blue
Color shifting but line seems the same:
- Loew Cornell Fine Point Marker
- Sharpie Ultra Fine Point Black
- Flying Colors Focus 0.5mm
- Corner Office Black
No change:
- Pentel Hybrid Technica
- Pentel Pocket Brush Pen (pentel ink)
- Permapague black fine point
- Faber Castell Pitt Pen Sepia
- Staples Gel mini- black
- Sharpie China Marker
- Derwent Graphitone
- Derwent Pastel Pencil
- Pelikan Fount India
The handbook paper which is acid free and a bright white color is now slightly yellowed.
