Pick trim/accent elements: After choosing your wall colors, your next step will be to choose trim and accent colors. Trim is typically painted in a glossy or semi-glossy neutral color, such as bright white or ivory, to provide a nice contrast to the wall color, creating a very formal look. Keeping the trim all one color provides continuity as you move from room to room. You may also choose to add accents to your walls and trim. For accents, it is recommended to choose complementary hues in different shades.
