Hi @stefancvrkotic Thanks for the feedback! I have just passed this on internally - I don't have a timeline yet by when this feature will be live but will be in touch on this thread when it's ready 
In the meantime can use custom CSS here and, for example, make the font white (yourSelector {color: white !important;}).
You can set this css dynamically and link the font colour to a variable that you can set via JS code - below is an example where the background colour of one record in a table is set via the variable background.
Also wanted to share some tips and tricks on how to use custom CSS in Retool apps with you, see here.
I hope this works as a temporary workaround
