The question is, why does the RLM 63 look so pale? And what color is the area under the '24' (which looks much more like the normal 63). Fading is not an adeqate explanation because worn and weathered RLM 63 looks patchy rather than faded (I've looked at hundreds of photos from the Spanish Civil War last night and couldn't find a single example of badly faded RLM 63).

BTW, there are six combinations of three colors without any mirroring:
61/62/63, 62/63/61, 63/61/62, 61/63/62, 63/62/61, 62/61/63
