It's nice to see that the two Andorras have a different take on their similar definitives. The French version has a different background colour for each value.

The Spanish version has the whole image in a different colour for each value.

I quite prefer the Spanish version. I like its simplicity, it works very well I think. The French version is a bit too colourful for me. Sorry guys! But then, (diplomatic like what I am) the version I like even more is the old French Arms issue of 1937-43. A lovely recess-printed stamp!
