Welcome to the Prismic community and thanks for reaching out to us.
It's not possible to retrieve documents the way you are doing. You can retrieve documents that have a specific by using predicates with Custom Types and fields If the document has a field name as "color," which is uniquely present in documents.
Unfortunately, you can not search the data content by Integration Field. I will make this a feature request for the future improvement and pass it to the @features-team.
