The red channel is probably overexposed, and blown. In LR, you have to 
reduce the saturation in the red channel. Best is to use the colour picker 
in the Color panel, and drag down on the colour you want to desaturate.

Converting the colour space can aggravate the problem, especially if you are 
converting into sRGB.
