 #   Global procedure. Read RGB color values from j1_colors.yml and returns
 #   the color found with liquid var color
 #
 #    Usage:
 #      1)  assign the 'color' variable to a color name. If the color (name)
 #          couldn't be found, the color given with fallback is returned.
 #      2)  include the select_color.proc procedure
 #
 #  Example:
 #
 #  {% capture select_color %}themes/{{site.template.name}}/procedures/global/select_color.proc{% endcapture %}
 #  {% assign my_color       = "md_indigo" %}
 #  {% assign color_fallback = "#FAFAFA" %}
 #
 #  {% include {{select_color}} color=my_color fallback=color_fallback %}
 #  {% assign my_color = {{color}} %}
 #
 #  or
 #
 #  {% include {{select_color}} color="md_indigo" fallback="#FAFAFA" %}
 #  {% assign my_color = {{color}} %}
 #
 # -----------------------------------------------------------------------------
 # Test data:
 #  {{ liquid_var | debug }}
 #  color:  {{ item[0] }}: {{ item[1] }}
