There is no way to get the *exact* same color in ACR as you get from camera JPEGs, because those are generated using Canon's proprietary color matrix and demosaic algorithm. However,you can change the camera calibration profile from "Adobe Standard" to "Camera Standard" (or "Camera Faithful" or whatever Canon picture profile you prefer) and that will help you get a little bit closer. If that color is important to you, I second the advice to use DPP instead of ACR.
