Replace colors swatch

Hi, i have a textarea with a list of color / hex value, example
negro #000
rojo #f00
blanco #fff

This value i convert to array with this:
assign colors = settings.swatch_colors_list | newline_to_br | strip_newlines | split: "
"

In each option values check if the option is Color then wanna check if the value color is in the colors array, i have this:

{% if option.name == 'Color' or option.name == 'color' %}
{%- liquid
assign colorp = value | downcase | escape | strip // THIS IS THE OPTION COLOR
for c in colors

  assign eachcolor = c | uniq | split: " #"
  
  for ec in eachcolor
    if ec[0] == colorp
      assign bg = ec[1]
    endif
  endfor

endfor

%}

data-color="{{ colorp }}"
data-bg="{{ bg }}"
{% endif %}

but simple i dont have put in bg the correct value :-( i try many options but i can't do it, can help me?

the idea is to have a textarea in the theme where the client can put a list of colors and this is replaced by a hexadecimal that he can put

Start by reproducing the Liquid template snippet with the textarea values and color options described in the issue. Trace how the colors array, eachcolor, colorp, and bg are evaluated. Done means the configured color name reliably maps to its hexadecimal value in data-bg.
