Color chart- Color Submittal form in customer portal

Would be awesome if the color chart is visible to the customer either on the proposal or through the portal. But what would be more amazing is if they could go to the portal and fill out a color submittal form, of them deciding, clarifying and putting to paper the colors they have agreed on to be used on the project. It could be the color chart but available for them to fill out. I will be doing this as I have had many issues with getting the colors locked down but would be stoked to do it on here!
