Diodes could be marked as you suggest. Some diodes have color bands for in 
house numbers that are not standard numbers. If your diode looks like a 
1N295 and tests like a 1N295, that is probably what it is. A 1N34 would be 
banded as black, orange, yellow.

See <http://www.crystalradio.net/cal/diodeid.shtml> for one diode color 
coding scheme.

Here is a document done by a military contractor to aid their maintenance 
people in the identification of a number of parts, a good reference
