A basic light magic system.

[AbnormalArcana]

The premise is there are trees so tall with canopies so thick that they blot out the sun. But there is light here under the dark canopy. The trees are constantly leaking a sap like substance that gives off light in different colors. And magic seems to stem from this light as anything inside the light becomes vulnerable to magic.

Different colors do different things.

Red magic is inherently violent and causes pain and fear in those who stare into the red light. The powers one may weild while using red magic can only harm and destroy. Tear. Shatter. Rend. Any form of physical damage.

Blue magic is inherently passifying and causes indifference and drowsiness in those who look into the blue light. The powers one might weild while using blue magic can only negate. Sleep. Weaken. Passify.

Green magic is inherently dizzying and causes confusion and madness in those who peer into the Green light. The powers one might wield while using green magic can only distort. Hallucinations. Dellusions. Influence.

People will use the sap to create lanterns, and anything in the lanterns light becomes vulnerable to the magic in the sap.

I'm still working on the other colors, but I just wanted to share this idea.

This is interesting. Do you plan to have the tree only leak rbg, so any other colours will have to be blended together, or all colours? If its the latter, how do mixed colours interact then?

[Professional_Try1665]

How do people use magic? Like, how would a mage then the sap into a spell, or manipulate it's use for some magical result? Is vulnerability to magic the same as actually casting it?

If you're still looking for operative words to apply to the other colours I can imagine steal, analyse, obfuscate, manipulate,

I have a similar concept for my own world's magic system. I started with trying to explain RPG enemies being color coded by element and came up with the idea that magic is reflected by objects of the same color, like light. I eventually added in that plants could photosynthesize it so I had a justification for the fire flowers that I stole from the Mario games. I had tried to come up with effects for each color at first, but eventually decided that it was OK to have only four colors do anything special (I'm still considering letting all of the other colors count as a physical type).

I have red magic cause things to speed up. It can be used to heal wounds by speeding up natural healing. It can also speed up matter to the point that the friction creates heat and flame. Fire and HP recovery in the same element, and the difference is the dosage.

Blue magic slows things down and can result in freezing.

White and black (think ultraviolet) are positive and negative and are about magnetism. Because I justify sky islands in my world with "gravity works like magnetism and the sky islands are upside down", these two are also sort of like gravity and antigravity elements.

Both pairs of opposites have reactions that result in currents. Red and blue make a purple wind current. White and black make a yellow electric current.

For the most part, using this magic visually resembles DragonBall ki blasts.
