Cosmic Serums are already made with safety and security by Sharat Sir.
So you don't need to use safety and security with Cosmic Serums.
Safety and security intention is required for exercise energy , gemstones , crystals , medicine energy and colors too.
When you use Cosmic Serums you may not need to use color energy.
You may not need more than one color anyway.
There are some contradictions in color therapy such as RED and BLUE cannot be used together as they produce opposite effect
It is advised not to use many colors together
