How do I sample a color from an image and apply it to template elements in Darkroom Core?
When building your template, anytime you see an option that has a color you can set that color to editable. This includes the background, effects, text as well as many other options.
You can also group element together by giving them the same name. This way you do not have to apply the same color to multiple objects.
When the template is loaded it will give you an option to scroll through you list of color editable objects (1).
If you click the eye drop you can then hover the image and click to sample a color (2).
