Conditional Formatting anomaly

[normpam]

In a cell you have in black font 'something', and then another word in a red font. I can use conditional formatting to make the cell font color, let's say, purple, but it only changes the black font word. Any ideas?

how can you conditional formatting with function, but this function have return value True, not yet? If return value False, so this cell will have font default.
