To paint a realistic oil rainbow on canvas, start by applying a soft gradient background to mimic the sky, using blues, whites, and hints of pink or lavender. Next, use a palette knife or brush to create the arc shapes of the rainbow, blending red, orange, yellow, green, blue, indigo, and violet in that order. Ensure each color transitions smoothly into the next, utilizing glazing techniques to achieve luminosity. Finally, add highlights and shadows to enhance depth and realism, and consider incorporating elements like clouds or a landscape to provide context.
