Transparent stickers

[Gerald Lasser]

Good, but that brings us back to the transparent sticker.

In fact,
If the transparent part of the topsurface of a sticker is allowed to use colour 16, wouldn't we break this rule?
Something is wonky here. The colour 16 is both allowed and not allowed.....

I think an opaque background should be made in the color of the sheet the sticker is printed on, e.g. White in this case.
Transparent stickers shall get color 16 IMHO, because I can then choose how I want to apply it, giving it the colour of the brick it is on or if it is a STAMP (sticker across multiple parts) I can give it the new transparent colour, right?
