Why spend hours digging through your closet trying to color-match the perfect outfit when with a little technology your clothing can match itself automatically?

If you're not afraid of tackling a little electronics, including wiring and programming (plus a little sewing) you can turn a ruffled scarf into a glowing accent piece that's always the perfect color thanks to a built-in optical sensor. The heart of the hack is a $25 FLORA wearable electronics board and the $10 sensor, but when you crunch the numbers it's still a lot cheaper than buying a separate scarf for every garment in your closet.
