The new field "Color" is great, but why not extend its selection interface to the other places of the application where you have to make a selection of color?
That is to say:
- In the selection of the background color of a library
- In the color section of a field source
- In the selection of the color of an element of a field "option button"
- In the selection of the color of an element of a field "list of a single option"
In this way the selection of the appropriate color would make it much more accurate by being able to manually select its hexadecimal value.

I would also like to suggest the inclusion of a new tab in which they store the user's personal color selections, in order to reuse them.
Thank you
