And, let’s be honest. I do knit with it a lot. Besides liking gray on its own, I think it's a great color to use when you want another color to really pop.
The other colors I’m drawn to are royal purple, kelly green and light pink.
If I look through my projects just at the things I've knit for myself, here is what I see.
Rampant socks (current knitting) - shades of dark pink, berry tones
The cabled wrap is gray.
The grieving socks are gray.
Flower Shower socks are gray.
Nori is a kelly-ish green.
Talamh is a lime-y green.
I've also done a couple of colorwork pieces recently that have lots of bright colors coupled with black.
When I think about sweaters I have planned, two are gray, and one is purple. For someone who likes light pink, I have surprisingly little of it in my knitting.
I've been working hard to not have so many variegated sock yarns in my stash. When I shop, I'm drawn to them. Then I have trouble finding a pattern that I feel shows up well within the color riot of the yarn. It's hard for me, but I have been working to buy semisolid colors.
I suppose the color gray fits in with the Manatee, which makes me feel a bit sad because it feeds into the stereotype of Boring Granny Knitter, the curse of the House of Manatee. I feel like I often have to explain myself when I say that my favorite color is gray. It isn't that I'm boring or afraid of strong colors. It's just that gray feels so comfortable, and it plays so nicely with other colors.
Then again, I probably shouldn't care what other people think, and being boring is misunderstood.
