translation from original Dutch: Fons Heijnsbroek
(original Dutch: citaat van Willem Roelofs, in het Nederlands:) Wij scheiden kleur en teekening af, omdat wij dat wel moeten. Maar de natuur doet dat niet. Zij geeft niet iets een vorm, om het daarna te kleuren. Vorm en kleur zijn inhaerente eigenschappen van het voorwerp, dat ons te schilderen is gegeven. Verwaarloozen wij een van beide, dan geven wij slechts de helft.
