Display Suite node field in layouts
My suspicion is you are having an issue because you are trying to access this in a Display Suite template, rather than from a page template.

You can probably access it via {{ ds_region.field_color.0 }} in the ds-3col.html.twig file. Some notes:


Replace ds_region with the name of the ds_region you want - e.g. middle.
The 0 will mean it prints the first item in the array - if you only have one item, this should be enough
You will need to have the field in the region on your Manage Display page.
Once done, you can then print {{ left|without('body') }}.
Make sure to clear your cache


I hope this helps.

You could also try to {{ dump }} the variables and see what is available for you (or better still {{ kint }} if you have the devel module installed), that will help you drill down through the options to get the one you need.
