In photography, how to construct cool and warm colors based on visual psychology?

Red, orange, and yellow are called warm colors. Warm colors have a strong stimulus to human eyes, and "warm" is the visual psychological feeling of the viewer. Warm colors are also called advance colors, because at the same distance, warm colors feel closer than cool colors. The warm color gives a feeling of forward and approaching.

Cyan, blue, and purple are called cool colors. Cool colors have a weaker stimulus to human eyes, and "cold" is the visual psychological feeling of the viewer. Cool colors are also called "fading" because at the same distance, cold colors feel farther than warm colors.

Hue refers to the color gradation or color tone formed by different hues, brightness, and saturation in a color photography picture. Focus on hue, use red, green, blue, etc. From the perspective of brightness, there are bright tones, dark tones, light tones, and dark tones. From the perspective of gorgeousness, there are fresh tones, gray tones, etc. From the perspective of human psychology, there are cold tones and warm colors. The hue itself is not warm or cold, and both cold and warm are human subjective feelings.

Warm tone, also known as warm tone. The color photography picture contains more tones of red, orange, and yellow. The warm tone can give people a sense of warmth, light, enthusiasm and joy. Ways to create a warm tone include: select a warm subject, place the subject under warm light at sunrise and sunset, shoot with daylight color film under a tungsten lamp, or adjust the white balance of a digital camera to daylight , Add red or orange filter to the lamp. In short, if the color temperature of the imaging carrier is higher than the color temperature of the scene, the color tone of the photo will tilt toward the warmer tone.

Cool tone, also known as cool tone. The color picture contains more tones of cyan, blue, and purple. The cold tone can give people a sense of coldness, coolness, calmness and openness. The methods to create a cool tone include: choosing a cool subject, shooting in daylight with high color temperature, shooting with a light-type color film in the sun, adding a blue filter to the lamp, and a blue filter to the lens. In short, if the color temperature of the imaging carrier is lower than the color temperature of the scene, the color tone of the photo will tilt toward the cool tone.
