I either have to match socks in the kitchen or try a different brand of CFL so see if the colours match after I get dressed.


First it was the temperature that affected them... pay the price for a decent CFL - IE Panasonic, which are rated for running in cold temperature.

Second, it was "colour rendering"... there is nothing wrong with the CRI of a CFL... the colour temperature of the CFL will affect how different colours look under the light... 27/2700K is similar to incandescent.. 35/3500 - close to halogen.. 41/4100K - cool white.

Incandescent lamps are not going to go away. The wattages changed and were lowered slightly to get around the legislation
