3D Customization page

I am now using Cyberfox 2D Canvas Editor to import and transform images in my 3d jersey customization page, my problem is, when I change the color of the jersey using the color buttons in my customization page, my imported image disappear. How can I change the color of my jersey without affecting my imported image??? What nodes should I use and how to construct it because I’m new to this shading part of the blender??? I watch the video tutorial of Cyberfox 2D Canvas Editor but it doesn’t work for me.
