Colourblind Test Acrylic Brooch

This broch looks like a classic colour blindness test, where numbers are embedded within a series of dots. The number and background colours are often difficult to distinguish for people with colour blindness, thus making the numbers difficult to make out. The dots are laser engraved and individually hand painted on white acrylic to display the number 42. The brooch measures 40mm in diameter, and is backed with a stainless steel brooch pin with rolling clasp.
