To be honest, an orange crystal could have an SSR, but not a 100% chance.

The color of the crystal indicates the rarity of what's inside the draw. An orange crystal will typically have SRs at the most. Lucifer (as both a character and summon) is an SSR, so you'll only see him inside a rainbow crystal.
