Suitable gradient color for packaging

Quick answer：

Gradient colors are often used in packaging design due to their visual appeal and ability to convey a sense of luxury or modernity. When choosing a gradient color for packaging, factors such as the product's brand identity, target audience, and the product's intended use should be considered. Bright gradients can evoke excitement and energy, while more subdued gradients can convey sophistication and calmness. The color choice should also ensure that the packaging is distinguishable on shelves and is attractive to the target demographic.
