Liquid paint has a different hue than dried paint. But even taking this into consideration, the Tamiya paint doesn't seem to be nowhere red enough.
Micro-Mark supposedly had Vallejo Acrylic paints custom mixed to replace the Floquil RR colors - you might try them.
Then there are Tru Color and Scalecoat paints too - I prefer either of those over Floqil (because they have semigloss ready-for-decaling finish). Once you try one of those (airbrushing), you will never used Floquil again.
