Although green and blue are not distiguished in Gurindji, they are in Gurindji Kriol. The Kriol words grin and blu are used. They are often nominalized with -wan but are also used as adjectives. Occasionally the Gurindji nominal wurrkal is used. However, this word has become semantically specified to meaning a 'green can', which is a specific type of beer.
