Можно ли изменить цвет шрифта в L6 в выделяемых строках (например в телефонной книге) со стандартного белого на черный или какой-либо другой? Если да, то как? Заранее благодарен за ответ.

Посмотри может это подойдёт.

Specify colors in spcolor.sch in hexadecimal RGB.
The offset specified is the starting point - each six digit color is actually stored in three successive offsets.
For example: offset 78, upper color bottom bar: if you want the color FF1432, put "FF" in offset 78, "14" in offset 79, and "32" in offset 7A.
Certain fields can have transparency - that is the fourth successive offset, specify transparency amount from 00 to FF. This will not work for all color settings.
