Stop doing that.
You have obviously no idea what the filters are doing and the result is ugly, many time worse than the original source (which actually looks ok).
At least you should read the filters/scripts descriptions, the result after the third line is identical to the result after the fourth one, you interpolate a field with nnedi3 (discarding half the vertical resolution in the process, because upscaling 480->wasn't enough) and then then interpolate it again in the next line.
Anyway, a basic upscale script should probably look like this

FFVideoSource("Input")
nnedi3_rpow2(rfactor=2)
LimitedSharpenFaster(dest_x=960, dest_y=720)

Read the filter descriptions and tweak how you see fit.
P.S. The color shift is probably due to the renderer switching from bt.601 to bt.709.
Another reason why you should not upscale if you don't know what you're doing.
