An applicator assembly includes a head portion having a proximal end, a distal end, and an interior portion defining a fluid chamber; a container for containing an antiseptic solution coupled to and in fluid communication with the proximal end of the head portion; and an application member in fluid communication with the fluid chamber and comprising a foam, having a first foam layer adjacent a second foam layer, wherein the first foam layer is disposed toward the distal end of the head portion and comprises a dye impregnated therein, and the second foam layer is disposed away from the distal end of the head portion and is free from the dye, and wherein, after the antiseptic solution passes from the container through the fluid chamber, the antiseptic solution passes into the first foam layer, whereupon the dye is solubilized by and tints the antiseptic solution.

1. An applicator assembly comprising: a head portion having a proximal end, a distal end, and an interior portion defining a fluid chamber;a container for containing an antiseptic solution coupled to and in fluid communication with the proximal end of the head portion; andan application member in fluid communication with the fluid chamber and comprising a foam, having a first foam layer adjacent a second foam layer,wherein the first foam layer is disposed toward the distal end of the head portion and comprises a dye impregnated therein, and the second foam layer is disposed away from the distal end of the head portion and is free from the dye, andwherein, after the antiseptic solution passes from the container through the fluid chamber, the antiseptic solution passes into the first foam layer, whereupon the dye is solubilized by and tints the antiseptic solution. 2. The applicator assembly of claim 1, wherein the first foam layer and the second foam layer and the second foam layer are integral. 3. The applicator assembly of claim 1, wherein a surface of the first foam layer contacts a surface of the second foam layer. 4. The applicator of claim 1, wherein the dye comprises an anionic dye or a cationic dye. 5. The applicator of claim 4, wherein the anionic dye is selected from the group consisting of: Blue No. 1, Blue No. 2, Green No. 3, Red No. 3, Red No. 40, Yellow No. 5, Yellow No. 6, Yellow No. 8, Orange No. 4, and combinations thereof. 6. The applicator of claim 4, wherein the cationic dye is selected from the group consisting of: crystal violet, acriflavine, bismark brown, malachite green, methyl green, Victoria Pure Blue BO, azure C, and combinations thereof. 7. The applicator of claim 1, wherein the antiseptic solution comprises an antiseptic agent and a solvent. 8. The applicator of claim 7, wherein the solvent comprises an alcohol selected from the group consisting of: ethanol, isopropanol, and n-propanol. 9. The applicator of claim 7, wherein the antiseptic agent comprises chlorhexidine or octenidine. 10. The applicator of claim 1, wherein the antiseptic solution comprises a solubilization aid. 11. The applicator of claim 10, wherein the solubilization aid is selected from the group consisting of: polyethylene glycol (PEG) average molecular weight 200, PEG average molecular weight 300, PEG average molecular weight 400, and glycerol. 12. The applicator of claim 11, wherein the concentration of the solubilization aid is about 1% v/v to about 49% v/v. 13. The applicator of claim 1, wherein the first and second foam layers independently comprise polyurethane foam. 14. The applicator of claim 1, wherein the first and second foam layers independently comprise hydrophobic or hydrophilic foam. 15. The applicator of claim 1, further comprising a filter layer disposed between the first and second foam layers that filters unsolubilized dye. 16. The applicator of claim 1, further comprising a wicking layer disposed between the head portion and the first foam layer. 17. The applicator of claim 1, wherein the container contains antiseptic solution. 18. The applicator of claim 1, further comprising an antiseptic solution releasing mechanism that releases the antiseptic solution from the container upon actuation. 19. The applicator of claim 1, wherein the first foam layer and the second foam layer comprise the same foam material.
