Hello, Greetings! of the day. I have checked attached image files. As mentioned in project description, and displayed in attached image files, your requirement is to implement following changes on product page on your magento website.
1) If product variant does not have image, then the color text should be displayed in product variant swatches.
2) If there are more than two product variants, which can be chosen, then only two product variant swatches should be displayed, the other product variant swatches should be displayed, when "More" button is clicked.
To implement this functionality, some code changes will need to be done. I have much experience in working on projects, using PHP, HTML, ecommerce, magento. Your work will be done, according to requirements.
Thanks.
