Hi Annie thanks for posting in the community! Unfortunately copying custom data from one shape to another is not currently supported in Lucidchart. It is also not possible to export color data using the export to CSV function. However if you copy and paste a shape that has custom data the custom data should be copied along with the shape.

We're always looking for ways to improve Lucidchart and your feedback is the best way for us to do that, so I’ve gone ahead and converted this to an idea within our Product Feedback space so that you and others can comment on and upvote it. Ideas shared here are passed on to the product development team for their consideration.
