WHY, just why...

Always wondered why the scope guys never
thought of using the resistance colour codes.
Maybe 2=red and 3=orange is difficult to discern.

For two channels there used to be a sort of standard:
L (1) = yellow and R (2) = red.
However, today many manufacturers have decided against this "standard".
Just look at your headphone, speaker outputs etc.

Brown, red and orange is a cruel joke for people with some variant of color blindness. A friend of mine who can distinguish neither green nor red once had to wire up a UTP cable, and to her the brown, red, orange and green wires all looked like shades of brown.

I wonder why they printed the first 2 Channels with black font, and the others with white font.

I think it's to match the color coding on the probes? In one case you have a dark pattern and in the other case you have a light pattern as a visual identifier in addition to the color.

Show me one oscilloscope from the other manufacturers,  that has a green color on a channel!
