If "Wide" Color Space is used, white balance can be left at the default 0. The "Color" parm just needs to be tuned down as shown below and it looks very similar in quality to Warm2 with Standard Color Space which requires White Balance tweaks.
Note: Most advanced options are turned off because they cause more artifacting, blur, etc.
