Yeah, sorting by color is a lot quicker than by part, though once you have things sorted by part (even roughly) it's easier to find placeholders that might not be the perfect color but still perform the same function. All those 1x1s could go in the same place and it would still help a lot with locating them, just knowing there's a place that only has 1x1s. If you're sorting to make it easier to build from instructions, sort by color. Otherwise sort by shape/size.
