Make the word a plural according to the noun in the sentence. Example, 1) zapatos (plural), blanco (singular). So the first one would be ‘blancos’ to match the form of the original word :) this also goes for the masculine and feminine forms of words!!
1) blancos
2)amarilla
3) negra
4)rojas
5) azules
6)morados
7) anaranjado
8) verdes
