Multicolor label

Hello everyone,
i want to know if there is an easy way to color a single label with multi color
for example :
" the Red is not Blue"
the bold words should be written by their color (red & blue)
currently am doing this with multi label but the positioning is becoming really painful specially that the words that must be colored are variables.
so i want if there is already a build-in way to do that or should i think to make my own ?

thank you
