How to Stop the overide of a product in the cart

[peachsnapple]

Hi, I have a coding problem. The way that I had it in the first coding example if a customer chooses two items of the same product but in different colors my code doesn't take that into consideration. It overides the same product information and just change the color instead of adding another line of the product with the different color. Instead of one line it should be two line with the same products but different color, but it does not show that way because the cart is being override by the new color added instead of making an additonal line of product with the new color.

 

My question and concern is, is there a way to write this page so that everytime a customer choose a product with an additional different color, a seperate line of the product with the new color will display?

Example:

Punk Hair - Red

Punk Hair - Blue

 

and not the blue replacing the red?

 

I really appreciate your time and help, thank you in advance.
