The colour was a mix of violet and black but maybe it needs a pearlescent paint in there to lighten, brighten and add some shimmer to the knots.
I constantly return to the choices I make with background colour and density and wonder if it were lighter then a better contrast between fore and backgrounds would be achieved. As ever the scarf is about to change again with fixing and wax removal as this lightens the lines and to some extend all the colours too. So the finished design will be paler.
Every design is a journey of choices which are irreversible and sometimes give unexpected results.
