i did it like you say...  "Folders" text colour and  the background color is same. to change "Folders" text color:
in reshack open shelstyle.dll and find "propertreeheader". at the first result like that:

</if>
<if id="atom(ProperTreeHeader)">
<Element background="argb(0,0,0,0)" contentalign="middleleft" padding="rect(9rp, 0rp, 0rp, 0rp)" />
</if>
<if id="atom(ProperTreeHeaderExpand)">
<Button background="themeable(dtb(PROPERTREE, PTP_FOLDERSHEADER, FHS_NORMAL),  window)"
foreground="themeable(argb(255, 94, 125, 166),                           windowtext)"
padding="rect(0rp, 6rp, 0rp, 5rp)"
/>
<if mousefocused="true">
<Button background="themeable(dtb(PROPERTREE, PTP_FOLDERSHEADER, FHS_HOT),     highlight)"
foreground="themeable(argb(255, 94, 125, 166),                           highlighttext)"
/>
</if>
<if keyfocused="true">
<Button background="themeable(dtb(PROPERTREE, PTP_FOLDERSHEADER, FHS_HOT),     highlight)"
foreground="themeable(argb(255, 94, 125, 166),                           highlighttext)"
/>
</if>
<if pressed="true">
<Button background="themeable(dtb(PROPERTREE, PTP_FOLDERSHEADER, FHS_PRESSED),  hotlight)"
foreground="themeable(argb(255, 94, 125, 166),                            highlighttext)"
/>
</if>
</if>
<if id="atom(ProperTreeHeaderCollapse)">
<Button background="themeable(dtb(PROPERTREE, PTP_FOLDERSHEADER, FHS_NORMAL),  window)"
foreground="themeable(argb(255, 94, 125, 166),                           windowtext)"
padding="rect(0rp, 6rp, 0rp, 5rp)"
/>
<if mousefocused="true">
<Button background="themeable(dtb(PROPERTREE, PTP_FOLDERSHEADER, FHS_HOT),     highlight)"
foreground="themeable(argb(255, 94, 125, 166),                           highlighttext)"
/>
</if>
<if keyfocused="true">
<Button background="themeable(dtb(PROPERTREE, PTP_FOLDERSHEADER, FHS_HOT),     highlight)"
foreground="themeable(argb(255, 94, 125, 166),                           highlighttext)"
/>
</if>
<if pressed="true">
<Button background="themeable(dtb(PROPERTREE, PTP_FOLDERSHEADER, FHS_PRESSED),  hotlight)"
foreground="themeable(argb(255, 94, 125, 166),                            highlighttext)"
/>



"themeable(argb(255, 94, 125, 166)"
expressions are changes the text color but i dont know which is highlight which is normal status.
so my "255, 94, 125, 166" color selection has same color as the background. you can change the "Folders" text color
by changing this arguments.

background is been changing in vsb. explorer&shell-->shell-->propertree
