Paint the walls of your bathroom with a warm, pastel shade of yellow. A yellow that is too bright will compete with the pink colors in your accent items. Darker yellows that have a heavier amount of orange tones tend to clash with pink shades. By using a light, pastel yellow, you can get away with pastel and darker shades of pink.
Display towels and washcloths on racks or in baskets. Use towels and washcloths that are primarily pink with touch of yellow or gold to pick up the yellow color of the walls.
Install window treatments that feature pink tones. Again, try to find fabrics that include a hint of yellow as well.
Place a pink soap dish and toothbrush holder on your vanity.
Add a vase of pink and yellow flowers to the vanity. Fresh flowers always brighten a room, and the pink and yellow color combination adds to the continuity of the room.
