My preordered TWBI ECO in yellow arrived in the mail today. YAY!!! I was thrilled to see that it wasn't a dull orange-yellow or an eye-stabbing neon yellow, nor yet a depressing school bus yellow (which never fails to look dingy to my eye). Nope! What I have is a sunny cheerful yellow. See it below! Now I just have to ink this pretty pen up ... but though I would like to use a yellow to yellow-orange ink (but nothing mustard-like) I don't know which ink I should use. Would anyone like to offer up any suggestions as to which ink I can pair up with my new pen? Please and thank you!
