When looking for inspiration today, I decided it was time to go RAINBOW for Pride Month. So I gathered all my pens and my favorite rainbow of inks.

What colors would be in your rainbow?
- Robert Oster Astorquiza Rot
- Robert Oster Peach
- Robert Oster Aussie Gold
- Papier de Plume Ivy Green
- Diamine Florida Blue
- Waterman Tender Purple

Also I guess I need a yellow fountain pen?

The newish Pilot Prera in yellow is a winner!
I spent a fair amount of time finding the right orange ink for my Pelikan M600 Vibrant Orange. You can simplify your own search by only looking at Robert Oster inks. They are reliably very orange and also dark enough to write with. Not sure how he does it, but that guy has orange sorted.
I currently bounce between Terracotta (a darker orange) and Orange Zest, mostly the latter.
