I remember seeing blue LEDs in a catalogue in the late

said something like "BLUE LEDs! Yes, *BLUE* ?30 (that's right, 30 quid)"
IIRC, the first blue LEDs were silicon carbide devices and miserably dim
compared to their red and green cousins. I suppose someone could have
created a full-color display with them, but it would have been expensive
and not very bright.
