I've designed a magic system and I'm wondering if it follows the property of entropy. it has eight different types of magic: lux, pyr, hydr, aero, necrom, terra, prestia, and bizarre.
The first six are known as the hexachromal magics, each being associated with color and the magics are attracted to those with the most similar colors and repelled by those that are the most different. Pyr is orange, hydr is blue, terra is green, lux is yellow, aero is red, and necrom is purple. There are also certain metals that interact with these magics, known as magimetals. Each one is associated with a particular magic and is attract strongly to it and repelled by the complementary color, with no interaction with those in between. gold has the property of being attractive to magic up to a point and then repulsive, making magic float above it in currents that move in a similar way to electricity. other conductors can have similar effects, but to a much lesser degree, and with a much more unstable equilibrium.
Prestia and bizarre are a pair, strongly attracted to one another, but their magimetals are strongly repelled to the opposite magic and attracted to the opposite metal. The magics, in turn, are strongly repelled by each other's metals.
Magimetals all weigh 45 kilograms per cubic meter at 0 degrees Celsius, and all the hexochromic magics are 0.04 kilograms per cubic meter under the same circumstances, with prestia and bizarre being 0.07.
Spells work by making the magic vibrate at a certain frequency, which directly correlates to its temperature, and use crystalline minerals that focus corresponding magics into a certain range of frequencies or temperatures. When magics that dont correspond to a focus are sent through, their frequencies are forced further away. The lower the frequency the magic moves at, the more 'sluggish' it becomes while inactive, so if you were to decrease the frequency of magic enough, it would act almost like a liquid, and be very cold due to frequency corresponding to heat. In a way, the higher the frequency, the more magic acts like a wave in a vacuum.
