I actually have a file on my laptop sorting my pens by color, just for curiosity's sake. Okay, it's really 2 files -- one is a list AND the other was because I was learning how stuff on iNumbers besides the spreadsheet function work (and am not a little OCD , so I have have bar and pie charts.
And I have zero pens that are orange. Not surprising, though, because I hate the color. Next would be pink (2), followed by yellow (3). Then there's a tie between metallic gold (as opposed to yellow -- it includes the 2 Morrison filigree overlay ringtops, and the "Champagne Gold" colored Jinhao 599), purple/magenta (which includes both the Lamy Safari Dark Lilac and the Parker 51 Plum Demi), metallic silver (separate from grey, the way metallic gold is separate from yellow) and Miscellaneous/Multicolored (which includes the Parker Vector which looks like it was stolen from a Mondrian painting, as well as the two [currently dead] Pilot Varsities -- but which does NOT include pens with metal caps or the late, lamented M200 Café Crèmes, because cream/brown is a category); all of those categories have (4) pens in them.
The most? Black (weird, because I'm not wild about black -- but when you find pens in the wild you don't get a choice... ) at 23 pens; followed (not surprisingly) by blue (at 18). I have enough teal and turquoise pens (such as the 2 51 Vacs in Cedar Blue, and the Teal 51 Aero) to have made them their own category. White and grey got lumped in together, but red and Burgundy didn't.
I have more green (8) and clear (12) pens than I thought; but most of the green pens are Esterbook J series Mackerels, and the reason I have as many clear pens as I do is because of the 5 Noodler's Charlie eyedroppers.
Mind you, this is all completely anecdotal evidence. I actually like yellow -- I just don't have many yellow pens....
