>Alchemic Light
There are various lights associated with transmutations. The first being yellow light. That is the most common amoung alchemists. Yellow light is associated with transmutations done through circles not on a person or on an article of clothing being worn. The second light is purple which occures when people do a general transmutation with a circle tatooed on them or on an article of clothing being worn. The third type of light is blue (Spoilers ahead highlight to read) which only happens when an alchemist has seen "The Truth" beyond The Gate. The final light is red which shines when a person is doing alchemy powered by the real (or fake) Philsopher's stone (a.k.a bypassing The Gate altogether and supplying your own source for transmutation energy)
. Other colored light comes up when a person a proficient at one aspect of alchemy like flames does a transmutation (orange for being good at flames, green for being good with plants ect)
>Alchemy Array Components

Below are some symbol that commonly appear in the transmutation circles and what they represent. Can you find which array uses them and how they relate to their function?

>Alchemy Arrays
Transmutation Circles are used by almost every alchmist to perform alchemy. They vary in shape and design. Many have idffering desings but have the same purpose. Though some circles do perform specific functions that other can not most of the circles pretty much allow the user the alter anything they have the power to change. The circles in red represent arrays that will only be done in blood. Below is an almost comlete list of the arrays seen in the series, check out the contest news on the home page to find out about the on going array contest. Also, none of the below images can be used on other websites without first gaining my permission. Thanks.
