Detecting colours of clothing

This can be done in one of two ways:

a. A colour detector which can be bought from the NCBI shop or

b. By stitching coloured shaped buttons onto garments. e.g., a button in the shape of a cross represents “red”, a clover shaped button represents “green” and a button with petals represents “yellow” and so on. These again can be accessed from the NCBI shop.

Self threading needles can also be had as well as needle threader.
