Lamy Copper Orange is my go-to fall ink. Not sure what I’ll use when it runs out.

Unfortunately we've been in a heatwave and drought here, so the leaves are just changing from dead to more dead. However I think I may bring out Noodler's Apache Sunset or Diamine Ancient Copper for my "walking around" pen.

Pilot tsukushi. Unfortunately not in production any more, but my bottle is pretty full.

@coys25 Yama-Budo and Momiji from the Iroshizuku line seem to be the default for many people, me included. But I’m low key on the lookout for more inks at the moment, so I’ll stick around and see other people’s suggestions.

My most recent ink purchase was Dominant Industry's Earl Grey Tea, and it's a beautiful orange shade that is well-behaved (albeit not quite as red as I was expecting when I ordered it). Absolutely no complaints - I even love the bottle, however I will probably get through it slowly because I don't often use colours that are bright and eye-catching.

By contrast, one of the inks that is in my permanent rotation and I plan to continue purchasing over and over is Diamine Saddle Brown. It's a more subtle, darker brown that can pass for 'serious' writing but still has a personality that I prefer over many other browns. If the orange of Earl Grey is a cozy Autumn fire, Saddle Brown is the tree branches holding on to their last leaves and the damp earth underfoot on a cold, foggy morning - both enticing in different ways.

Diamine Honey Burst and Robert Oster Red Orange are the perfect colors for autumn leaves :)

Diamine Autumn Oak, Montblanc Corn Poppy Red, Montblanc Golden Yellow. I'm not sure which if any of these are still being made though, probably not the yellow.
