Blue-green picture solid color

Quick answer：

A blue-green picture solid color refers to an image that is uniformly colored with a shade of blue and green. This could be an artistic choice, a branding element, or a way to convey a specific mood or concept. In digital imaging, achieving a solid color involves setting the RGB (Red, Green, Blue) values to create the desired hue. The term 'solid color' also implies that the color is not mixed with other shades or gradients.
