Red and blue gradient color formula

Quick answer：

A red and blue gradient color formula typically involves blending red and blue hues in varying intensities to create a smooth transition between the two colors. The specific formula can vary widely depending on the desired color range and intensity. For example, a basic gradient might start with a deep blue and gradually blend into a bright red. This can be achieved by mixing different shades of blue and red pigments or by using color mixing software that allows for precise control over the gradient's hues and saturation.
