Add color list option in attribute's design option.

Hello Team

We greatly appreciate the ability to set unique color sets for each attribute along with MSPC, as it provides flexibility in design. However, we believe it would be even more efficient if there were an option to add or choose colors from a predefined color list, just like the color list function in product builder.

In cases where multiple attributes share the same set of colors, adjusting the colors individually can become quite time-consuming, especially when making small changes to the color set. Introducing a color list option within the attribute's design settings would streamline this process and significantly enhance usability. This update would be a highly valuable improvement.
