The usual warm colors in the color wheel are mainly red, purple and yellow-green are neutral colors, and blue is cool. For example, if you draw a single red apple as a warm tone, if you match it with a set, you should determine the tone according to the color of a large area. The color of each still life is complex but regular. For example, draw a dark part of an apple. Red and grass green are the inherent colors of the apple, as well as environmental colors (colors reflected by the interlayer in the set) and light source colors (lights or natural light). As for what you said, "Do the dark parts of objects match warm colors?" My answer is "not necessarily", because it depends on the ambient color, light source color and inherent color.
