I got this ink sample a while back and I’m sorry I took such a long time to get around to it. Diamine Amber straddles the line between yellow and orange in a way I really like. It shades even in my Visconti EF nib though only subtly. It’s such a bright and happy colour that I can’t help but smile when I use it. It goes from a pale sunrise yellow to a strong muted orange colour.
