Form "BackColor" not matching HEX values

I am trying to make my forms in VBA to match the color of SolidWorks feature tree background.  The HEX color according to my image program is: E2E4EC.  I input this into the "BackColor" field in VB but the color doesnt match.  Are colors limited in VBA?  If not, any ideas why this isnt working?
