Why my taxonomy term list in content is not using node languages prefererence
Check the "translation mode" that you've specified within admin/structure/taxonomy/colors/edit (whereas "colors" is the name of your specific category): by default that is set to "Localize", though it should be set to "translate".

After changing this value, be aware that you then also have to:


enter a translated value for each of the tags and
revisit any of the existing nodes that are already using the specific taxonomy, so that they use the (translated) term that corresponds to the language of the node.
