I'm trying to add 'pp. ' to the following paginations but it doesn't work:
grep -n -o -E --color "\b(pp.\s)?\d{1,3}–\d{2,3}\b" references.txt
3:pp. 610–623
5:102–114
8:58–70
10:245–258
12:99–120
13:70–86
16:172–195
18:389–399
25:1–13
27:104–117
29:503–516
38:501–507
40:1–14
42:450–470
46:759–785
49:1–14
53:50–62
56:1–17
59:1–17
the first pagination (pp. 610–623) is already written as is in the text, this is how the others should be written.
here is the command used:
sed -E "s/(\b(pp.\s)?\d{1,3}–\d{2,3}\b)/(pp. )\1/g" references.txt

No modification is made to the text and I don't have any errors either.
Your regex is wrong. This should work:
sed -E "s/:(pp\. )?(.*)/:pp. \2/g" references.txt
If you want to change the file in place, you should add the -i flag too:
sed -i -E "s/:(pp\. )?(.*)/:pp. \2/g" references.txt
Also, the first optional capture group (pp\. )? is present only because you said that the first line already had pagination, so I thought other lines might have it too. If you manually added that and no line has pagination, you can as well remove it:
sed -E "s/:(.*)/:pp. \1/g" references.txt
