Issue description

If a colorpicker is configured to allow for transparency option (which comes as an extra two hex digits when formats = hex or "all") the value of this field with opacity at the end can never be saved as it doesn't pass the built-in validation.

Steps to replicate

1. Create a form field of type colorpicker, configure it with showAlpha: true.
2. Try to submit the form

Workaround

No known workaround
