The red being torn, like the innocent lamb. The purple veil being torn revealing the glory of God. They seem to be shadows of the cataclysmic events of Good Friday. The sun went dark, an earthquake occurred, He was pierced and blood and water gushed out. The passion of Christ fulfilled both the justice and the love of God in one event.
It is true that we have all sinned, but God showed His love toward us in that while we were yet sinners, Christ died for us. The righteous given for the unrighteous, making a way for all to enter into a new relationship with God. Do you see what I see?
