What’s the best way to color match my main cam and B-cam for a consistent grade?

I’m trying to get better at matching the color and feel between my main camera and my B-cam footage, but my shots still look like they’re from two different projects. I’ve been working with scopes and trying to build a consistent base grade, but something in the midtones and skin tones just never quite lines up, even after a lot of tweaking.

I pinned exposure and WB on both cams with a gray frame, then applied a single base grade to both feeds. Midtones got matched with the same curve on each clip and I kept skin tone nudged just a touch away from saturation. It helped, but when the B-cam moved into a different light angle the look still drifted.

For me the lighting is the stubborn part. Even with numbers aligned, a shift in key light or practicals makes skin tones read differently. I tried lining up on a neutral frame and then rebalancing in post, which helped a bit but never fully steadied it.

I once chased the perfect histogram and ended up with washed out skin on the B-cam. I stepped back, locked a simple base grade, and compared skin tones side by side on a neutral shot. That change reduced drift but I still saw it when the camera moved or the sun changed.

What feels bigger to you, the lighting setup or the camera profiles when you try to line them up?
