I'll respect your decision to restrict your choices and limit the
size of the toolkit. But when you want to move up from DV you're
going to find the choices very limited...
A wise craftsman knows 1) to use the proper tool to do the job and
2) welcomes a larger toolkit even if that means combining free and
commercial tools.

Actually it wouldn't be the histogram that's used when doing
color correction. It'd 1) use the vectorscope, and 2) an external
calibrated monitor.

None that are compatible with your philosophy ;) Besides color
correction needs to be done scene by scene in many cases (you do need
to make sure that scenes "match" so that you don't have disruptive
chroma shifts between scenes) using an external monitor - NOT just
stuffing a command in the encoding pipeline.
Oh, the tool that could do it IF you could see what you're doing to
arrive at the correct parameters is 'yuvcorrect'.

Aieeee - you can NOT and should not under ANY circumstances use a
computer monitor for color correction. But you know that NOW :)

Not just luminance. It's the color range that can be displayed.
TVs do not handle highly saturated colors well either.
Something like a Sony PVM14L2 (which is what I use) is a good
inexpensive production monitor.
