text_A: For Ingres, colour played an entirely secondary role in art. He wrote, "Colour adds ornament to a painting; but it is naught but the handmaiden, because all it does is to render more agreeable the true perfections of the art. Rubens and Van Dyck can be pleasing at first sight, but they are deceptive; they are from the poor school of colourists, the school of deception. Never use bright colours, they are anti-historic. It is better to fall into gray than to into bright colours." The Institute in Paris complained in 1838 that the students of Ingres in Rome "had a deplorable lack of knowledge of the truth and power of colour, and a knowledge of the different effects of light. A dull and opaque effect is found in all their canvases. They seem to have only been lit by twilight." The poet and critic Baudelaire observed: "the students of M. Ingres have very uselessly avoided any semblance of colour; they believe or pretend to believe that they are not needed in painting."
text_B: Would Ingres have taught his students in depth about the skill of how colors complement each other?
NO.
