If you have an issue with your website product images being different colors to your uploaded images its generally to do with color profiles and the wonderful world of CYMK and RGB.
This is generally a result of images being provided by a photographer for print, and then trying to use them on the website.
In short CYMK colour profiles are for Print and RGB is for web
Images need to be exported for use on your Storefront Admin in RGB with no colour profiles.
Generally you will need to ask your photographer or image supplier to provide these in RGB format.
