How To Reduce Colour Swatches On Product Collection Page? - Impulse Theme

[JordanM]

Hello,

I would like to include product color swatches under the products in my product collection on the Impulse theme. The problem is that all the colors are appearing which makes the collection look overcrowded. Check the image below:

As you can see too many colors are appearing. I would like only 4 swatches to appear and the rest to be + (all rest colors), like the image below:

How can this be done? Any help would be appreciated!
