Gradient array from blue to red

Quick answer：

A gradient array from blue to red refers to a sequence of color values that gradually transition from blue to red. In digital media, such as graphics or web design, this can be created using hexadecimal color codes or RGB values. The transition typically involves blending the color blue (e.g., #0000FF) with red (e.g., #FF0000) over a range of values. This can be used to create smooth transitions in visual content.
