The color fades on the blue-green gradient

Quick answer：

The phenomenon described refers to the 'fading' of a blue-green gradient, which is commonly observed in printed materials or fabrics. It occurs when the dyes used in the manufacturing process are not colorfast and can be washed out or fade over time. This issue is particularly relevant in the fields of graphic design, printing, and textile manufacturing, where colorfastness is a critical factor for the longevity and durability of products.
