Question with antimatter theme and his color filter

Hi, I’m newbie,
How I can disable the color filter with the antimatter theme?
Thx in advance for response

You mean in the showcase right?
If so, go to user hemes\antimatter(or your custom theme) emplates\modular\showcase.html.twig,
and change the first line to suit your needs. I just left it like this:

{% set showcase_image =|first %}

Perfect, thanks for your response.
