This is a wet, dark brown ink. Though it’s dark, you can still make out the brown tones of the ink. Though it’s named walnut, I think My Dudek Modern’s Goods Block’s walnut looks redder. Noodler’s Walnut is a dark ink but it has subtle shading property. It goes from a deep dark brown to a grey-brown colour. Noodler’s Walnut is a nice colour but it’s a little too wet for me to use. It would be better paired with a dry nib. My thanks to Louisa for the ink sample.
