Detail of the Annunciation

The wings of Archangel Gabriel look soft and strokeable. Van Eyck achieves this effect thanks to, among other things, his incredibly nuanced colour palette: he manages to blend colours in a subtle way. Aliki van der Kruijs, Wim Goes and Wonmin Park also do this, but they each use very different methods and materials.
Van Eyck first painted the white feathers, and then added other colours on top this in very thin layers. Contemporary designers and artists, for example, Elena Gileva also use layers to create colour nuances.
