Cantonese + Mandarin tone coloring

I never really paid much attention to the colors, but my Cantonese reviews always feel so bland compared to Mandarin and i think it's due partially to the lower-quality TTS for Cantonese and the fact that i didn't have tone coloring enabled for Cantonese. I enabled that today and even though i don't really pay much attention to the actual colors, my reviews don't feel so boring. However, this overwrites my Mandarin reviews as well (so that they are using Cantonese tone colors). Is there any way to select which tone coloring to use via flashcard settings (similar to how i can chose to force Cantonese audio in my Cantonese flashcard settings) so that one doesn't override the other?
