Here is a link to a letter Lord Byron wrote, whilst in Italy. https://www.bl.uk/collection-items/letter-from-lord-byron-to-douglas-kinnaird-about-other-poets He's using dark brown ink. Could anyone suggest a brown ink that would look similar in colour to this? I'm thinking Waterman's Havana Brown is probably too light - and Platinum's ink cartridges is close, bust still not quite dark enough. Does anyone have a suggestion? It's difficult to get an idea looking at ink samples on the screen. Thank you.
