How to add Product Default Image Thumbnail as Available Colors for Related products On Product Page

[Univmentor]

Hello Every One !

 

 

I want to display Also available in these colors option on my product page to my customers. So that they can select the different color of same design from product page it self. 

 

 

---> I know one way of doing this is using texture for color instead of  solid color box.[This doesn't suit my need]

 

​I have uploaded different colors  of same design as  different product[diff SKU].

 

 

 Pointers for creating this module will be appreciated. 

 

 

Please have a look at my dev environment link.
