We opened a PTR to request a field type that would cover color. This field type could be used in product options for sellers to define colors as options.
We received the following response:
The Color Field type was included in the Data Engine to attend the needs of migrating WEM and D&M to the new Form Builder, however, we also thought that this field type would be valuable enough to have in Forms and App Builder as well.
Right now, the Color field is already available in Forms (in master and DXP 7.3), however, it still need some adjustments in order to be available for the App Builder too. I have talked to Eduardo Zoby and we will create a Story to make those adjustments and have it ready on App Builder.
The idea is, from now on, any new field type created in Forms should also be available in the App Builder (except when the field doesn't make sense for an App building purpose).
Review what's already been developed and planned to be developed to see if it will meet Commerce's needs.
