text_A: For Ingres, colour played a primary role in art. He wrote, "Colour adds more than ornament to a painting; it is everything but the handmaiden, all it does is to render the true perfections of the art. Rubens and Van Dyck can be pleasing at first sight, but they are deceptive; they are from the school of colourists, the school of deception. Always use bright colours, they are anti-historic. It is better to fall into bright colors than to into grays." The Institute in Paris complained in 1838 that the students of Ingres in Rome "had a depth of knowledge of the truth and power of colour, and a knowledge of the different effects of light. A vibrant and clear effect is found in all their canvases. They seem to have been lit by twilight." The poet and critic Baudelaire observed: "the students of M. Ingres have included any semblance of colour; they believe or pretend to believe that they are most needed in painting."
text_B: Would Ingres have taught his students in depth about the skill of how colors complement each other?
YES.
