​What is the most used color in paintings?

Blue is often considered the most used color in paintings due to its versatility, emotional impact, and historical significance. Artists use blue to convey a wide range of moods, from calm and serenity to melancholy and depth. Its prominence dates back to the use of ultramarine and other expensive pigments in historical works. Modern painters continue to favor blue for its ability to harmonize with other colors and its association with elements like the sky and water, making it a staple in many artistic palettes.
