Colours

When you collect stamps and you are also colourblind you have a sitiation. Did find these Dutch Trixins (free by machins!!) in my collection. These are no two issues in different colours. Just one did stay to long in the sun or so. On ANSC there was= a discussion about scanning stamps. I think that scanning is not a problem, but our nice sun is. Not for us, we need it badly, but some stamps are not happy with sunlight. Could not say if this one was in the sun, maybe it happens with soaking or ??? The same stamp, you know what is the right colour?
