However, there's a foot-gun in the first paragraph. In the mid-nineties practically no one was using "black and white" monitors. I remember a few ancient DOS test-only stations at a school and a single amber-monochrome hardware terminal (connected to big-iron at work) in that time period. Everything else doing real work was Win3.1 and color Mac by then. Netscape browser had already dropped and was popular; no one was using it in black and white.
This was in California. May be slightly ahead, and I'm not taking developing countries into account. But color was so compelling it was already not-uncommon by the late 80s.
