Feature request: "Color picker" column

Hi there retool team,

As there is a lot of opportunity to customize based on colors, it would be great to give users the option to select their own colors.

Not sure how complicated this would be, but I thought of a new column type for tables which is a color picker (identical to the one in all of the components' "Styles" section.

This would allow for an easy capture of preferred columns in database and loop it back to custom preferences in components.
