Pelikan M620 Athens, M605 14K Fine, inked with Bookbinders Snake Ink Red-Belly Black
The blue-green-yellow banding makes for a very good looking pen. Though I expect to spend half my time trying to get the cap and body bands to align. Darn OCD.
The silver trim of the Athens allows me to use the full rhodium plate fine nib that came with my M605 Transparent White pen late last year. This nib is a nice wet writer.
Black must be the most boring ink colour that I own. No shading, no sheen, just a consistent black line time after time.
