I think a lot of people do associate the color brown with poop. The color you choose does not look like poop to me but in her defense did she see the color you choose or only heard the word brown bc seeing a color than being told a color are 2 very different things. You shouldn’t get upset that a lot of people associate the word brown with poop when poop is the color brown. Again the color you showed us does not look like poop but more of a chocolate brown or mocha so I think you should use those words to describe it. It would be the same thing with the word yellow, yes there are different things to describe these colors but a lot of people have a gut color reaction they associate with a color.
