Pantone's Turquoise: the "colour of the year" for 2010
Difficulties aside, turquoise makes a great accent colour for a black and white decor, and also for a dark brown and beige decor. It compliments well with various shades of dark blue and with soft yellows too. With some caution, it can be paired quite successfully with pink.
For inspiration to introduce turquoise into your decor, look at the Arts & Crafts movement, most notably motifs by William Morris; Moorish and Mediterranean decor, especially the tiles and inlaid work; and c. 1950's accessories to name a few.
