Hi, I have a some problem when create an plugin.

on backend, I have a image field and color. The 'color' is based on dominant color from the image. How to implement this case? FYI, on front end, I can do that because I have a control before or when the image uploading. So I can get the 'color' using 'color thief' package.

So, please tell me how to to that on backend. Because on backend the process is like a magic. :)

Thanks

you can manipulate your data in the model event described here : http://octobercms.com/docs/database/model#model-events
