Thank you for replying, everyone. ^_^
Oh, hey, that sounds like a neat ink. I'll have to look for it. I'll bet it's been reviewed here. Thank you for the suggestion, Runnin_Ute. ^_^
Beautiful color! Congratulations!
Thank you, GardenWeasel!
Yellow ink is quite difficult to see. Use it's compliment - Violet
Oh, that's a good point. I should have thought of that. Hmm ... which violet should I use, then?
Diamine Sunshine Yellow? Diamine Amber? Iroshizuku Yu-Yake?
Ooh, Sunshine Yellow! I've seen that color and I think I have a sample of it somewhere. I remember it's a really bright yellow. Diamine Amber and Ir. Yu-Yake are two I will have to look up. All three sound divine!
Ordered mine yesterday. I was thinking about Diamine Golden Sands. It is a shimmering ink which may or may not be an issue.
I was thinking of this too! I thought I could very carefully draw ink from the top of the bottle *without* getting any shimmer and then I'd be set. If there is any drawback to the TWSBI Eco--and it's a very small, practically insignificant drawback--is that there isn't any way to bypass the nib and feed to get to the ink chamber without disassembling the pen at the back end. Compare this to my Diamond 580, where I can unscrew the feed and squirt ink into the chamber with a blunt syringe. It's a simpler method but I adore my Ecos because they aren't fussy and write so well.
