By "orange" I think Electronic M probably meant warm white (is that correct, or really orange?).
Regarding failure:
White LEDs consist of a blue LED chip with a phosphor to fill in the rest of the spectrum. It is possible for the phosphor to degrade over time, changing the color of the light somewhat. Some white LED backlight strips for LCD monitors/TVs have shown a failure mode in which some individual LEDs become dark blue. This has been discussed online (here or on YouTube, I don't recall), but I have not seen an explanation of the failure mechanism.
