Hello,
you mean the yellow keyboard legends, right?
Your frequently used HP-11C was made 1986 (as you say), and the latter one was mad in 1983.
There's a chance that these units have a totally different inner layout, regarding the pcbs, battery and LCD connections.
Depending on the production year and materials used, colors may vary to a certain degree.
If you compare HP-41CV units of every single production year, you'll notice slightly different keyboard legend colors, too;-)

Hi;
I have two HP16C´s. In one of them (oldest) the [f] functions are printed in pale yellow, and in the other one (newest) they are in fairly visible orange. Both are US-made.
Cheers.
