That makes me wonder... why do all scopes still have a dark background? I did some TFT conversions on old test equipment and in those cases I always went for a white background. It is much easier for the eyes.
White is a typical color for general PC usage ...
When using this on a scope you´ll get problems with the coloring of the waveforms ...
Colors like pure yellow, green or cyan won´t work that good due to their high brigthness on contrast to the white background.
And reducing max. intensity for them will loose step within the color scale for dark to bright.
Otherwise you´ll need a complete different color set for white background ... which might be good for the color blind people.
Can somebody post a shot of a picoscope?
PS: my eye specalist once said: the more change you give to your eyes the better it is ... ( esp. if working in front of monitors )
