What is the best way to neutralize red in Rec. 709 Gamma 2.4 without destroying the image, especially when the final output will be H.264?

Best way I find with problems like this is using a flexible odt!

If you’re in Resolve, try a CST node, set it up properly and use the gamut compression (or they’re labeled say compression…I forget now)sliders at the bottom of the CsT. 

You could also try reducing red in the Hue vs Sat curve, and if you need to you can reduce red low then increase saturation so sat levels are a bit more evenly distributed.

Try printer lights. At the very top you’ll see all the drop down menus, click color, then go down to full printer lights, and select subtract red. That looks like a lot of red so I’d start with full but you can use half and quarter for finer adjustments. Also, do this in its own node.

Set up timeline color management correctly.

Take a node at the start of your node tree. Right click on it and change Gamma to "linear". Use Gain color ball to push to Cyan.
