Any tips for creating more pleasing looking color from on camera flash

I’m using negative lab pro v.2.4.2 and I am noticing I’m having trouble replicating the look of the on-camera flash shots my lab used to give me. I like to shoot Fuji Superia 400 in a point-and-shoot when I go to see bands. NLP can make the objects closest to the flash look washed out (like a neutral LOG even when I am doing LAB-Standard) and a bit blue. Menwhile my lab scans look simultaneously warm and pink without going purple. Any tips? Thanks!
