Rainbow Upgrader

"A rapidly color-changing upgrader that upgrades ore from 5 to 100% depends on the color of the upgrader. Doesn't upgrade ore worth more than $100M."

Overview
The Rainbow Upgrader is a Premium Tier Upgrader that randomly changes the amount it upgrades ore by based on its color. It can upgrade ores from 5% to 100%. It has the same design as the Large Ore Upgrader. Unfortunately, this upgrader only goes to 100M so players don't use it much as a Freon-Blast Upgrader is more effective.
