Here is an example from an application I wrote. It has some glade-specific
code lines, but the general idea is the same:

void setcallstyle(gint row) {
  GdkColor color1, color2, color3, color4;
  GtkStyle *newstyle;
  GtkWidget *log;
  
  log = lookup_widget(mainwindow, "logclist");

  /* set colors */
  color1.red   = 0x0000;  /* light blue */
  color1.green = 0x0000;
  color1.blue  = 0xcd00;
  color2.red   = 0xffff;  /* white */
  color2.green = 0xffff;
  color2.blue  = 0xffff;
  color3.red   = 0xcccc;  /* light gray */
  color3.green = 0xcccc;
  color3.blue  = 0xcccc;
  color4.red   = 0x4924;  /* dark slate blue */
  color4.green = 0x3cf3;
  color4.blue  = 0x8e38;
  /* set style of the new row */
  newstyle = gtk_style_copy(log->style);
  newstyle->base[GTK_STATE_NORMAL] = color1;
  newstyle->fg[GTK_STATE_NORMAL] = color2;
  newstyle->bg[GTK_STATE_SELECTED] = color3;
  newstyle->fg[GTK_STATE_SELECTED] = color4;
  gdk_font_unref(newstyle->font);
  newstyle->font = gdk_font_load("-adobe-helvetica-bold-r-*-*-*-120-*-*-*-*-*-*");
  gtk_clist_set_cell_style(GTK_CLIST(log), row, 3, newstyle);
}
