Assign certain product and then show them in grid

So what I am trying to do is to get Products based on a COLLECTION and TAG and then later on display them in a grid style. I'm kind of new to the ASSIGN function and other ways to make some more advanced features.


I am trying to add this to a product page. I know this is wrong and that is needs some kind of handle (I now get 'ProductDrop'), but whatever I try it will not display them.


{% for product in collections.frames.products %}
{% if product.tags contains 'Color_Grey' %}
{% assign color_grey = product %}
{% endif %}
{% endfor %}

 and then:

{% for product in color_grey %}
{% include 'product-grid-item' %}
{% endfor %}
