Custom colorpicker for Wordpress for paint-selling webshop (Woocommerce advanced colorpicker)

Please read description carefully. Go check out this product: [login to view URL] (ALL LOGINS ARE READY FOR YOU: Login: /[login to view URL] User: a****** Pass: $B**************) NOW: Go to the field “Vælg variant” (below the green button - meaning choose variant). Farve = Color When clicked, there is a pop-up where the client can choose a color. When the color is clicked, it is saved and chosen as the color of the color (a woo commerce variant) and is displayed in both cart, checkout and the order. The client is a paint seller, where on some of the paints, the client can choose the color themselves. Then he mixes is. So my thought is, that in Wordpress backend, when adding a variant in Woocommerce (adding product -> variant), there should be a checkbox “Display colormap” and if that is checked yes, then the color map popup is shown as a color variant along with the size variant (how many liters of paint they will buy). We have full access to the current site that has the color picker, and also the new wp-installation that needs the color map. But SADLY, we dont have ftp-acesss to the old site. So only admin access, and then i hope you can find the codes somehow or see how its made. It needs to be exatly like it is now in the popup - or something very similar. It is important that: It can be checked on or off per product. It will popup when it is on, and when the color is chosen, then it should be displayed as a variant (so the seller can see what color the client chose in the order. Deadine is three days. If you perform well, we have tonnes of more work - our current freelancer is not reachable, and therefore we need a new web-partner. We have about three wordpress client pr. week. New page is [login to view URL] and is using flatsome theme with woocommerce. You will get login admin wordpress, ftp and mysql to this if wanted.
