SHAOSExperiment with color combination with chess board mixing:
This is simulation in DOSBox on PC:
PIC32 on NTSC TV - palette 0:
PIC32 on NTSC TV - palette 1:
PIC32 on NTSC TV - palette 2:
PIC32 on NTSC TV - palette 3:

Also DOSBox can't properly simulate some color combinations for example 0001 and 1000 combination turned on NTSC to something similar to 1001 (green), but DOSBox is still showing mix of green and blue pixels...
Are you sure? yes | no
If you compare 1st image (DOSBox CGA composite simulation) with 2nd (actual NTSC palette 0) you can see that NTSC interprets colors on diagonal from lower-left to upper-right corners as gray most likely because of "comb filter" in modern TVs (when every scanline is combined with previous 1 or 2 scanlines to avoid color artifacts).
