graduated color blocks on poster

Quick answer：

Graduated color blocks on a poster refer to a design technique where different shades of a color are used to create a smooth transition or gradient effect. This visual element can be used for aesthetic purposes, to draw attention to certain areas, or to represent a concept such as progression or change. In graphic design, creating a graduated color block can involve blending colors from light to dark or vice versa, often using software tools to achieve a seamless blend.
