I have been working on Chakras for years and now believe I have been doing it incorrectly!

This is what I have been using (I believe I got it from a website)*
*Colors per text color


CROWN Chakra - Top of head (Magenta or gold or white)
BROW - Between Eyes, third eye
THROAT - Bottom of throat where ribs begin
HEART - Center of chest
SOLAR PLEXUS - Where ribs end
SACRAL - Just below belly button
ROOT - Base of spine tailbone

I now see that most say:

CROWN Chakra - Top of head (Purple)
BROW - Between Eyes, third eye (Lt. Blue)
THROAT - Bottom of throat where ribs begin
HEART - Center of chest
SOLAR PLEXUS - Where ribs end
SACRAL - Just below belly button
ROOT - Base of spine tailbone

Can someone confirm which is correct? I have also wondered why the ROOT is located around, behind (so to speak) at tailbone, and not in line up front with others??

Now today while researching this, I come across a Reiki teacher stating that the ROOT is actually at the ankles !! That many have been wrong for years.

Please someone clear this up......
