@Jongware – I think Robert wants to limit the GREP style to the first line of a paragraph.

But unfortunately GREP in InDesign does not know about line endings.

In scripting we could do something like what he wants, but comes with some obstacles, because the GREP will apply a character style, that will probably change the line ending. A very dynamic situation…

Example 1

Basic situation:

This is my text here comes the colon: and

here another one: that Robert don't like

to take into account using the GREP style.

Formatted after  the GREP style is applied:

This is my text here comes the colon: and

here another one: that Robert don't like

to take into account using the GREP style.

As I understand it, in case that the first colon will leave line one, only the first line should be formatted like this:

(Case 1)

This is my text here comes the first

colon: and here another one: that

Robert don't like to take into account

using the GREP style.

Or should it be, that the style should only be applied, if it's in the first line?
(Case 2):

This is my text here comes the first

colon: and here another one: that

Robert don't like to take into account

using the GREP style.

But what, if the colon in the basic case is at the end of line 1 and will be shifted to line 2 after formatting?

What should happen then?

That is simply not possible to format automatically (dynamically) using GREP styles in InDesign.

@Peter – I assumed this because of:

So now I'm wondering how to limit the grep to the first line

in #4.

I could be totally wrong…

Yes.

If a "Nested Line Style" could overwrite a "GREP Style", we could manage that, but "unfortunately" that isn't…

Not working example:

GREP Style:

Apply Style: "BoldFont_CharacterStyle"

To Text: ^.+?:

Nested Line Styles:

[None] for 1 lines

"RegularFont_CharacterStyle" for 999 lines
