Can we somehow use custom colors?

Is there a way to change this? If i turn on the unknown don’t learn word color then my unknown words become white which is also annoying, I have the special word option turned on but it does absolutely nothing I have no way to mark words like this, this is quite annoying because my language is full of English loan words and names that I don’t need to learn but the color choice is super annoying so I just end up putting all these useless words in the known words category just to not have to deal with the color.
