May I aslo add, that as s a student of iconography I was taught that: Christ always has a cross in his halo and the letters for “I Am”, or "The One Who Is". His inner garment shows His inner being, that is, a red (human)+ violet (heavenly father)= the ground pigment of hematite, which is also interestingly called bloodstone. His mission is shown by his outer garment, a green + dark blue =a deep aquamarine indicating his mission is to deify humanity, to bring us all to theosis. The golden sash is a sign of royalty. Hope that helps!
