hair color

Hello everyone I have been wanting to dye my hair or put highlight or
just certain spots died. But a few questions. I baught Loreal Paris
Feria Colour Strandws C90 Quickshimmering highlights for natural medium
to dark blonde hair. I want peoples opinion if that color would go good
with dark brown hair. If not what color or product name would?? Also If
it does go good is the Loreal Paris Product I mentioned washable? can
it be shampooed or some other chemical to wash it out or is it
permanant? Well let me know. I would prefer if you emailed me at
mlfen22@frontiernet.net. Thanks!!!
