The six yarn colours you can see in the picture are those I selected among the natural colours of the beautiful Shetland sheep:

Shetland white*

Shetland black* (very dark brown)

dark brown

light brown

dark grey

light grey

*NB Shetland white isn’t pure white but a natural shade of the Shetland sheep which is off white, a light cream/ivory colour. Shetland back is actually a very dark brown, the natural colour of the Shetland black sheep.
