【HELP】How To Edit the Floor's Lines' Colors By HEX?

As the subject ,who can teach me the concise way to solve this question , i want to change a Floor's Lines' Colors and i have known should use the HEX ,but i do not know where the position of the colors in a floor.iff ,so If U know this ,can U tell me ? i will give U much more thanks to U ,please help me ,thanks to all the NLSC's GUYS. ~~~~~~

the location of the line colors change with each floor file, so it might be in one location for one file, and another for another.

I do not have the line colors mapped out for any floor, it's just a matter of looking at the hex coloring tutorial in the Tutorials forum and figuring out what colors change the lines.
