Can we change the color of the subtitles?

[WINSEVN]

I would like to change the color of the subtitles from red to some other color that is easier to read. Any mods available that do this?

I suggest using Google honestly that usually gets the job done quickly.

Nothing related to Portal

This page details exactly what you should be doing, just doesn't have the Portal specific filenames.
Under Portal\portal\resource edit closecaption_english.txt (make sure to back it up first, as well as closecaption_english.dat)
Notice that the Glados captions have <clr:219,112,147> at the beginning - this is the "pale red violet" color which the titles use. You need to replace the numbers according to whatever RGB color you want (https://www.w3schools.com/colors/colors_rgb.asp)
Then you need to compile the file according to the instructions. Your compiler can be found under Portal\bin\captioncompiler.exe .
This will produce a new closecaption_english.dat with the titles in the chosen color, once you're done with it you can restore the backup (alternatively, you could place the new dat in a "custom" folder, but I don't know if that's relevant to your need).

Thank you so much for explaining it to me. That helps.
