Color Picture of pi camera

1- The color Picture of my pi camera is something like red, although I’ve tried using this command :
camSet=‘nvarguscamerasrc wbmode=3 tnr-mode=2 tnr-strength=1 ee-mode=2 ee-strength=1 ! video/x-raw(memory:NVMM), width=3264, height=2464, format=NV12, framerate=21/1 ! nvvidconv flip-method=’+str(flip)+’ ! video/x-raw, width=‘+str(dispW)+’, height=‘+str(dispH)+’, format=BGRx ! videoconvert ! video/x-raw, format=BGR ! videobalance contrast=1.5 brightness=-.2 saturation=1.2 ! appsink’ .
to increase accuracy but it doesn’t make any sense.

2- Also, my Pi Camera v2 accuracy is very poor, it can’t focus !!!

Do you have any Idea??
Thank you

Does below command the same?

gst-launch-1.0 nvarguscamerasrc ! "video/x-raw(memory:NVMM), width=(int)3264, height=(int)2464,format=(string)NV12, framerate=(fraction)21/1" ! nvvidconv ! xvimagesink sync=false

Thank you,
i applied the command but I get invalid syntax !!!
