Only show color swatches if more than two colors

Store Design
1

Hi! We have the color swatches on our products and collection pages but would like to only display the swatches on the collection page when there are more than 1 variant of colours to a product? Because we are also including a separate filtering by colour, we are ending up with one swatch on products that only have one colour. (which is currently turned off at the moment)

{%- liquid

  assign option_name = option.name | downcase
  assign color_swatch_options = "color, colour, couleur" | split: ", "
  assign current_option = "option" | append: option.position
  assign other_options = "option1 option2 option3" | remove: current_option | strip | split: " "

-%}

  

**{{ option.name }}:** {% for value in option.values %}{% if option.selected_value == value %}{{ value }}{% endif %}{% endfor %}

  {% for value in option.values %}
    {%- liquid

      assign image_url = value | handle | append: '.png' | file_url
      assign css_color = value | split: ' ' | last | handle
      assign available = false

    -%}

    
    {%- liquid

      assign available = false

      for variant in product.variants
        unless variant.available
          continue
        endunless

        unless variant[current_option] == value
          continue
        endunless

        unless variant[other_options[1]] == current_variant[other_options[1]]
          continue
        endunless

        unless variant[other_options[2]] == current_variant[other_options[2]]
          continue
        endunless

        assign available = true
      endfor

    -%}

    
    {%- liquid

      for variant in product.variants
        unless variant[current_option] == value
          continue
        endunless

        unless variant[other_options[0]] == current_variant[other_options[0]]
          continue
        endunless

        unless variant[other_options[1]] == current_variant[other_options[1]]
          continue
        endunless

        if variant.image
          assign variant_image_url =  variant.image | img_url: '100x'
        endif
      endfor

      assign checked = ""

      if current_variant[current_option] == value
        assign checked = 'checked="checked"'
      endif

      assign swatch_img = null
      assign swatch_color_name = value | handle | append: '.png'

      if images[swatch_color_name] != blank
        assign swatch_img = swatch_color_name | file_url
      endif

    -%}

    {% capture radio_button %}
      
    {% endcapture %}

    {% capture sold_out_image %}
      
    {% endcapture %}

    {% capture regular_swatch %}
      

        {{ radio_button }}

        
      

    {% endcapture %}

    {% capture color_swatch %}
      

        {{ radio_button }}

    {% if show_color_swatches and color_swatch_options contains option_name %}
      {{ color_swatch }}

I believe the Dawn theme does it by wrapping the variant selects/swatches in the following unless statement:

{%- unless product.has_only_default_variant -%}
Your code here
{%- endunless -%}
