The colors red and yellow are primary colors in the additive color model, meaning they cannot be created by mixing other colors. Red is often associated with strong emotions like love and anger, while yellow is linked to happiness and warmth. Both colors are vibrant and can easily attract attention. In art and design, red and yellow are frequently used together to create a sense of energy and excitement. When mixed, they produce orange, another secondary color. These colors are also commonly found in nature, such as in flowers and sunsets, enhancing their visual appeal.
