I love this ink!
Purple has always been my favorite color. For inks, I’m particularly drawn to purple inks with grey undertones. RO Charcoal is very dark purple with greyish undertones. It’s really...view more pretty. Because it’s so dark, another name could be Halloween Purple.
When it’s not shading, the ink is nearly black. I’m currently using it in a TWSBI Diamond 580 ALR: Purple (medium nib).
I find a TWSBI Diamond medium nib is great for showcasing the features/characteristics of most inks. Shading, flow, feathering, etc. view less
