How can I efficiently add image swatches to Dawn product pages?

I am writing to seek your assistance regarding an issue I am encountering with adding image swatches to Dawn’s product page. Initially, I utilized meta fields to accomplish this task; however, with our client’s extensive inventory of over 16,000 products, each with a multitude of variants, this method has become impractical.

I am reaching out to you guys to inquire if you have any suggestions or solutions that may prove more efficient in addressing this matter. Your guidance in this matter would be greatly appreciated.
