There is a mired shift calculator here
If you gel the flash (assuming ca 5500K) to match your LED you could use a Lee 285 + 206 on your flash, then WB your camera for the 2700K.
This is a very good tool.
It reminds me of the detailed filter packs we would create for our color critical clients when shooting film. Buy the film by the case, arrange for lab to process everything with neutral chemicals, and also buy photofloods by the case for consistent color lighting.
All that because once the film was exposed and processed, the only way left to color correct was in pre-press and that could add significantly to separation costs for a catalog.
Today we have the white balance eye dropper, DNG profile editor, color checker charts.
For an event, unless its for a dress designer that is paying lots to get perfect color rendition on their garments, 1/2 to 3/4 CTO and go.
