Independent Living Skills Specialists (I believe American usually use the term Rehab workers, rather than ILSs) teach a few different methods for identifying clothes. One common method is to sort out what matches well with each other, and then use a safety pin with beads on the inside to identify. For example, maybe one bead means dark colours, while two beads mean light colours, etc. There are also little braille tags that can be sewn in, or little shaped buttons that can also be used to identify colour in a tactile manner.
Colour detectors can be useful, but there are some issues with them. They are not always correct (I've had them detect my skin as ranging from green, to blue, to chartreuse). And depending on the lighting, it can change the perceived colour. They also doesn't work so well with a shirt that has multiple colours (such as a Hawaiian shirt).
