convert RGB to CMYK colorspace

I tried to convert a RGB tiff to CMYK tiff with the following command:

convert RGB.tif -colorspace CMYK CMYK.tif

Somehow, the colors are skewed. The light blue becomes dark blue color.

How to correct this effect? I need to color to be exactly the same after conversion.

Thanks
