Combine Individual Product Listings for different colors

Hi everyone,

I have 4 individual listings for a women dress that comes in 4 different colors like Green, Red, Yellow and Black.

I made 4 separate product listing instead making a single listing with 4 color variants…

Now, I want to link all 4 listings from each other by showing color choice on each product page, something similar to this: https://jisora.com/products/vibrant-serenity-cotton-coord-set

They have 4 different listing for all the 4 colors but there is a color choice option that seems similar to color variant picker ..

Could anyone suggest the best way to achieve this with Dawn theme…?

Thanks !
