Blue gradient value

Quick answer：

The 'blue gradient value' refers to the range of blue hues and intensities in a gradient. In digital design and graphic arts, a gradient is a smooth transition between two or more colors. The 'blue gradient value' could be specified in various color models such as RGB, HSV, or HSL, where the value for the blue component (B for RGB, V or S for HSV, L for HSL) varies to create the gradient effect.
