Select Field with 2 font colours

Hoping to style the Select Field without creating a drop down menu from scratch. :crossed_fingers:

We would like the font colour for ‘I feel’ to remain grey as it is now. When user selects any of the other choices i.e happy, sad or tired, the font colour will change to black.

We thought of using mouse click trigger, but obviously we can’t select the drop down choices as triggers…

Anyone got a solution?
