Results in March 2025

After 18 months in the sun all inks with bright colors had faded, even the ones made with pigments.

These were lightfast, eg had not faded:

• Platinum Carbon Black
• Noodlers Black Eel
• Noodlers Heart of Darkness
• DeAtramentis Document Fog Grey
• DeAtramentis Document White
• Winsor & Newton Calligraphy ink Gold
• Winsor & Newton Calligraphy ink White

The Diamine Grey had only faded a little bit. I had expected Platinums Brown (Brun) and Platinum Rose Red to have faded less than they did since they are pigment inks.
