Show tone colour for headwords in tests without revealing the full pronunciation


Hi everyone!

I was wondering if there was a way to show the tone colours of a chinese headword during flashcard testing without having it show the full pinyin pronunciation. I'd like to visiually train myself to know the colours of the characters without necessarily spoiling the pinyin right away. I have tried the different options in the subject configuration tab of the test settings, but didn't manage to find what I wanted.

Has anyone here ever tried something similiar and has maybe found a solution?

Many thanks!
