I work exclusively with color and assuming this doesn't already exist and I just can't find it, I'd really love a way to input a specific color value to select only pixels matching that exact value rather than a range.
But in Photoshop, the magic wand tool can do that by setting the tolerance to zero, set it to point sample, and turn off antialiasing. Contiguous can be on or off depending on whether you want to select connected colors, or all colors in the image that match that value.
Hey thanks! I'm using the latest creative cloud, Photoshop specifically. I wasn't talking about selecting a single color by clicking on it with a tool but being able to input the color you want (like with hexidecimal or lab values etc.) and have every pixel matching it selected.
