Not being on Instagram, I couldn't access that (although I did notice that they were using the Pantone matching system. As for the Benjamin Moore site, I wasn't finding the questions part, just looking at the different swatch families. For paint, it depends entirely on the use of the room I'd be painting, and (to some extent) the general decor. My house was originally built in the 1880s, so I found a book at the library on what paint/wallpaper shades would be "correct" for houses of different eras. I wouldn't normally pick a mustard yellow -- but it would be "right" for my house -- and in fact we found some wallpaper up in the attic that had mustard yellow and a very slightly blue leaning dark green (also found on the fireplace tiles) that I suspect was original to the house (without being home to actually compare the palettes I'd say that it would be somewhere between B-M O Forest Green, Sherwood Green, and Ocean Tropic). The previous owners painted EVERYTHING white -- including right over the wallpaper ... probably just to put the house on the market (I can't really fault them for that, other than ruining what was nice wallpaper; my parents apparently did that in the living room of the house I lived in when I was little because the previous occupants put up this horrid jungle print wallpaper with leaves that were at least 8" long -- I've seen photos; it just screamed early 1950s and was pretty hideous looking). But the OLD wallpaper was actually nice (if we had the money we'd replace it with the really expensive wallpaper that is based on Arts & Crafts design period wallpaper). When we redid the kitchen, the walls and floor tiles are white, simply to get as much brightness into the room as possible (it's on the northeast corner of the house, and we also added a bay window to get as much afternoon light as humanly possible).
As for inks, I'm all over the map. I love blues, and blue blacks (especially ones like Edelstein Tanzanite that don't lean teal), and pinks (if they're not too pale and "girly" looking) and all sorts of purples (from red-violets through middle of the spectrum purples to some blue-violets) and a number of greys. I tend to prefer slightly yellow-leaning greens over the bright or blue-leaning greens. I like TRUE reds (fire engine, color of my first car reds) way better than burgundies or the blood-red ones, or the orange or brown-leaning ones) but I also like some of the very slight pink-leaning ones). I don't like most teals, I mostly don't like oranges, and I don't mostly like red-leaning browns. And while I have a bottle of Noodler's Bay State Blue, I don't really care that much for the color -- it leans a little purplish for my taste (I know, after having just said I like blues and purples). I have a couple of golden inks I like but I haven't found a yellow ink that was legible on the page (I'm fussy about yellow to begin with -- I can't wear the color at ALL but love bright yellow flowers and would dearly love to plant an 'Austrian Briar' rosebush (in spite of the tendency toward blackspot, and the difficulty in obtaining a true 'Austrian Briar' for anything resembling a reasonable price) -- I had a 'Persian Yellow' at one point and it bloomed once before biting the dust, and the flowers where what I'd call "Crayola Yellow" ('Austrian Briar' is the species form, with a five-petaled flower; 'Austrian Copper' is the sport that has yellow on one side of the petals and this weird bright orange-y color on the other side of them; and 'Persian Yellow' is the multi-petalled version). And I like sepia browns way better than red- or orange-leaning ones (except for Diamine Terracotta, which I do like a whole lot). I almost never use black but there are some greys I would never want to be without.
So my ink palette is all over the map.... On this trip I have pens inked up with Edelstein Smoky Quartz, original formula Sailor Sky High, vintage Quink Permanent Royal Blue, vintage Quink Microfilm Black (which leans blue), Nemosine Alpha Centauri, and Straits Pens Storm Warning (a slightly greyish green ink that was one of the Central Ohio Pen Club LE inks from the Ohio Pen Show last month); and while I haven't inked up a seventh pen yet, I brought along a sample of Birmingham Inks Gunpowder Tea for "just in case"....
