As it happens, I'm not designing anything right now, seeing as how I'm still moving/lacking most of my furniture. I'm also not decorating with black and yellow, but for some reason, I have rather a lot of it laying around. So I piled it all in one place (hoping against hope that it would resemble a couch). And then I went in search of other, better-composed palettes.
A pile of similarly colored items in my apartment.
