That is true, a warm white led gives the best colours through the tricolour lens.Also I recall, if converting a white incandescent bulb ( atop mast with coloured lenses) to led , one has to use the correct type of led , warm white iirc. The cool white will produce a non conforming colour through the lenses.
Please double check as I may have got this information from a man in the pub.
