Quoting someone from there:
Beige was the only color case available until around 1992
Yep, the best you could do then in RGB was Rich Glossy Beige. 😛
Although having submitted a rather glowing review of the oven, it doesn’t seem to have exhibited any of the smooth breaking in of the previous model. Did ask about the magnetron, – from that there certainly seems to be a chance of a better response elsewhere. 😛
