The absorbent article provides a signal viewable from the top surface of the absorbent article which gives a perception of depth within the absorbent article. This creation of depth perception is accomplished by the use of at least two tones within a color and/or by the use of multiple tones and multiple colors operating together to create a perception of depth within the absorbent article.

1. An absorbent article having an upper surface, a lower surface and a periphery, the absorbent article comprising: a white topsheet having a bottom surface and a viewing surface positioned opposite to the bottom surface, the viewing surface facing upwardly towards the upper surface of the absorbent
1. An absorbent article having an upper surface, a lower surface and a periphery, the absorbent article comprising: a white topsheet having a bottom surface and a viewing surface positioned opposite to the bottom surface, the viewing surface facing upwardly towards the upper surface of the absorbent article;a backsheet having a garment facing surface and a user facing surface positioned oppositely to the garment facing surface, the backsheet being joined to the topsheet;an absorbent core having a top surface and a bottom surface positioned opposite to the top surface, the absorbent core being positioned between the topsheet and the backsheet;the topsheet having colored portion printed thereon, the colored portion having a first shade printed on a first area of the topsheet and comprising a plurality of first printed marks, and a second shade printed on a separate area of the topsheet and comprising a plurality of second printed marks, the first shade and the second shade being the same color, the second shade being different from the first shade in lightness, darkness, and/or tone. 2. The absorbent article of claim 1, wherein the first shade and the second shade operate to create a perception of depth within the absorbent article by a user looking up the viewing surface of the topsheet. 3. The absorbent article of claim 1, wherein the first shade is positioned substantially within the second shade. 4. The absorbent article of claim 1, wherein the first shade is positioned substantially centrally with respect to the second shade. 5. The absorbent article of claim 1, wherein the first shade is positioned substantially adjacent to the second shade. 6. The absorbent article of claim 1, wherein the first shade, the second shade, and a non-colored portion have L*, a*, and b* values that are measured by a reflectance meter. 7. The absorbent article of claim 6, wherein the L*, a*, and b* values of the first shade and the second shade are measured at a first point within the first shade and a second point within the second shade on the viewing surface of the topsheet inboard of the periphery of the absorbent article, the L*, a*, and b* values being used to calculate a ΔE* by the formula ΔE*=[(L*x·−L*y)2+(a*x·−a*y)2+(b*x−b*y)2]1/2, wherein the ΔE* between the first shade and the second shade is at least 3.5. 8. The absorbent article of claim 6, wherein the L*, a*, and b* values of the first shade, the second shade, and the non-colored portion are measured at a first point within the first shade, a second point within the second shade, and a third point within the non-colored portion on the viewing surface of the topsheet inboard of the periphery of the absorbent article, the L*, a*, and b* values being used to calculate a ΔE* by the formula ΔE*=[(L*x·−L*y)2+(a*x·−a*y)2+(b*x−b*y)2]1/2, wherein the ΔE* between the first shade and the non-colored portion is at least 6. 9. The absorbent article of claim 6, wherein the L*, a*, and b* values of the first shade, the second shade, and the non-colored portion are measured at a first point within the first shade, a second point within the second shade, and a third point within the non-colored portion on the viewing surface of the topsheet inboard of the periphery of the absorbent article, the L*, a*, and b* values being used to calculate a ΔE* by the formula ΔE*=[(L*x·−L*y)2+(a*x·−a*y)2+(b*x−b*y)2]1/2, wherein the ΔE* between the second shade and the non-colored portion is at least 3.5. 10. An absorbent article having an upper surface, a lower surface and a periphery, the absorbent article comprising: a white topsheet having a bottom surface and a viewing surface positioned opposite to the bottom surface, the viewing surface facing upwardly towards the upper surface of the absorbent article;a backsheet having a garment facing surface and a user facing surface positioned oppositely to the garment facing surface, the backsheet being joined to the topsheet;an absorbent core having a top surface and a bottom surface positioned opposite to the top surface, the absorbent core being positioned between the topsheet and the backsheet;the topsheet having a colored portion printed thereon, the colored portion having a first shade printed on a first area of the topsheet and comprising a plurality of first printed marks, and a second shade printed on a separate area of the topsheet and comprising a plurality of second printed marks, the first shade and the second shade being the same color, the second shade being different from the first shade in lightness, darkness, and/or tone, andwherein the colored portion has a shade gradient of the color. 11. The absorbent article of claim 10, wherein the first shade and the second shade operate to create a perception of depth within the absorbent article by a user looking up the viewing surface of the topsheet. 12. The absorbent article of claim 10, wherein the first shade is positioned substantially within the second shade. 13. The absorbent article of claim 10, wherein the first shade is positioned substantially centrally with respect to the second shade. 14. The absorbent article of claim 10, wherein the first shade is positioned substantially adjacent to the second shade. 15. The absorbent article of claim 10, wherein the first shade, the second shade, and a non-colored portion have L*, a*, and b* values that are measured by a reflectance meter. 16. The absorbent article of claim 15, wherein the L*, a*, and b* values of the first shade and the second shade are measured at a first point within the first shade and a second point within the second shade on the viewing surface of the topsheet inboard of the periphery of the absorbent article, the L*, a*, and b* values being used to calculate a ΔE* by the formula ΔE*=[(L*x·−L*y)2+(a*x·−a*y)2+(b*x−b*y)2]1/2, wherein the ΔE* between the first shade and the second shade is at least 3.5. 17. The absorbent article of claim 15, wherein the L*, a*, and b* values of the first shade, the second shade, and the non-colored portion are measured at a first point within the first shade, a second point within the second shade, and a third point within the non-colored portion on the viewing surface of the topsheet inboard of the periphery of the absorbent article, the L*, a*, and b* values being used to calculate a ΔE* by the formula ΔE*=[(L*x·−L*y)2+(a*x·−a*y)2+(b*x−b*y)2]1/2, wherein the ΔE* between the first shade and the non-colored portion is at least 6. 18.
