Hi,
I am having an issue with colour matching using prismic. Images that I upload are coming out darker and bluer than I designed on the front end of my Gatsby site, which is an issue if your trying to match flat colours between videos and jpegs. After testing via screenshooting and looking at them in photoshop, they appear to be this way in the media library also. So my question is, is there a way to turn off the image compression or whatever prismic/imgix is doing at the point of upload to get colours exactly the way that I designed them?
Best, Theo

Hello Theo,
Welcome to the Prismic community, and thanks for reaching out to us.
Prismic image compression is done with the help of [Imgix](http://www.imgix.com/) image processor.
Color changes can be due to compression. You can turn off the compression to figure out the reason.
