  We present measurements of two-color X-ray free electron laser (FEL) pulses
generated with a novel scheme utilizing a sextupole magnet. The sextupole, in
combination with a standard orbit control tool, is used to suppress the
radiation from the bunch core, while keeping the head and the tail of the beam
lasing, each at a different photon energy. The method is simple, cost-effective
and applicable at any repetition rate. We demonstrate the tunability of the
scheme and discuss its advantages and practical limitations.
