We’ve built our Gravity Forms Color Picker add-on off the back of our popular Image Choices add-on for Gravity Forms. Our Color Picker add-on works straight out of the box and works in the same manner that Image Choices does. Simply tick on the ‘use colors’ option when you add any checkbox or radio based field. Gravity Forms Color Picker supports radio fields, checkbox fields and single text line fields.
Gravity Forms Color Picker add-on lets you bring a whole new life of colour to your forms. Let users select from a pre-defined set of swatches you make available or even let your users select a custom hex value from the colour picker.
