The highlight lines of the wings are done with a colour composed of pure kitrino with a point of yellow chrome – this colour can also be obtained with the following mixture: a point of Naples yellow, a point of yellow chrome and a small point of vermilion red – The mixture must be quite dry in order to obtain precise lines while doing the tracing.
After tracing the highlight lines, it is possible to retrace them using the technique of gold assist...
The lines of the wings will be retraced with some red ochre and the extremities of the feathers will be accentuated to give them movement.
