thanks a lot for the reply and the hint to the code. As to the code: I have a text and I want to change the color of all lower case consonants within the text (whereas the color of the remaining letters shall remain as it is). More specifically, I want to change the color of the letters from white to black (it is a ppt with black background). The idea is to get a text with missing letters that have to be completed by the readers (but can be shown if needed). Does that help or would you need more specific information?

best
