I haven’t yet tried it myself, but I read on another thread that Benjamin Moore has an app for this on their site.

Here's the one for Sherwin Williams. https://www.sherwin-williams.com/visualizer#/active

These applications might give you somewhat of an idea, but there is no substitute for sampling outside. Natural light simultaneously washes colors out and also brings out undertones that you might not have otherwise been aware of. Plus colors on the north side will look very different on the south side of a house.
