Claim 0:
1. A package of absorbent units, said package comprising:
an outer enclosure enclosing said absorbent units, the outer enclosure including a dominant area that is at least partially non-opaque,
wherein said outer enclosure has a thickness which is less than approximately 70 μm, and
wherein the dominant area of the outer enclosure is at least partly of a first predetermined colour as defined in the L*a*b* colour space, and
the absorbent units are at least partly of a second predetermined colour in the L*a*b* colour space as viewed through the first predetermined colour of the dominant area of the outer enclosure;
wherein:
the absorbent units have at least one lightly coloured or light grey area, and
the dominant area covers a substantial part of the outer enclosure and has a lightness value above 75 in the L*a*b* colour space, and
a magnitude of a colour difference between the first colour of the dominant area and the lightly coloured or light grey area of the absorbent units, as seen through the first colour of the dominant area of the outer enclosure, is less than 7,
wherein the magnitude of the colour difference is determined by the following equation:

ΔE=√{square root over ((L*1−L*2)2+(a*1−a*2)2+(b*1−b*2)2)}.
