I've made changes to the color scaling for a number of the weather parameters and it appears that the temperature and dew point temp color scaling is the same or share the same color scale.
The change I made to the temperature scale was linked to the dew point temperature display and for my setup carry the same scaling across both parameters.
You just have to be a bit clever in how your break up the colors for both parameters.
Unless anyone else has found another means to separate the two scales?????
