warmer or cooler than another? There are three possible definitions of "warmer": (1) contains more yellow; (2) contains more scarlet (red); (3) is closer to gray.
If you want to convey luminance, then yellow mixtures and yellow bias in reflectance curves is the key; you need to know how to increase or decrease those in any color by paint mixtures and how to harmonize the yellow content of paints in a total painting.
if you want to convey dryness, lack of moisture, heat, intensity, then the same is true, only now your focus is on red (any scarlet or red with no blue reflectance cadmium red deep is ok, quinacridone red is not).
