Luxin Magic

Luxin Magic is an old magic that allows its mages (or, as they are formally known as, Drafters) to create physical structures by solidifying fight (although that is an extremely basic explanation of its inner workings). There are seven primary colours (Superviolet, Blue, Green, Yellow, Orange, Red, and Sub-Red), and they all have different properties, and all impact upon one's emotions.

Description
A simple explanation of how Luxin Magic works is simple: "When a candle burns, its physical substance is turned into light. Drafters merely do the opposite: they turn light into physical substances." However, if the Drafter doesn't have enough of their respective colour then they won't be able to draft any Luxin (the substance they create from light). An example of this would be if a Yellow Drafter being in an entirely red room, with no yellow in it at all, then they would not be able to draft any Yellow in that room. And the amount of Luxin that can be produced is dependent on the amount of that colour that it is in the room; for instance, if a tiny piece of yellow fabric was in the aforementioned room, then the Drafter would be able to create some yellow, but the amount would be small and not as high quality as that created in an entirely yellow room.

All practitioners of this magic have an alignment towards a specific colour, or multiple if the user is either skilled enough or naturally aligned towards multiple colours (the amount of colours increases with rarity, unless the person is the Prism). Any Drafter who can drafter is known as a polychrome, but the amount of colours they can draft changes their title; for example a Red and Green Drafter is known as a Bipolychrome, whereas a person who can draft all colours is known as a Full Spectrum Polychrome. A Drafter can gain an auxiliary colour if they go through intense training (which involves the person temporarily losing all sight, then being allowed to see but their vision is only their desired colour, and then being forced to draft in these conditions, hopefully resulting in them gaining a new affinity to the colour), but there is no assurance of success. And even if they are successful, their prowess with the colour will normally be second rate when compared to Drafters who draft the colour naturally. But for a person who can Draft multiple colours naturally their skill with their colours is only limited by their skill and power.

The Prism
There is only a single Prism in each generation, they are a person that is able to draft every colour without any chance of breaking the halo. Their skill with each colour is supposed to match that of masters of each colour, but the truth of the matter is unknown (although most Prisms are master Drafters). A unique feature of the Prism is that they have eyes that shimmer through the colours of the electromagnetic spectrum, from the deepest blue to their fiercest yellow.

Superviolet
One of the more rare colours due to a person having to dilate their pupils to inhuman extents to even see the colour, Superviolet is invisible to all except those who Draft it or Sub-Red. This colour can be used to create invisible (to the general populace) structures, invisible writing, traps, and various other uses. Superviolet is one of the more fragile colours (as it will shatter against a bullet, for example), but it can still cut through flesh with ease.

The emotional effect of drafting this colour is that Superviolets tend to have a removed outlook. They appreciate irony and sarcasm and are sometimes cold.

Blue
A versatile colour, Blue allows for its Drafter to create hard, chalk-like constructs. The creations will be quite hard, allowing them to be used for things such as weapons or armour, but are quite brittle. Unlike metals, Blue will shatter under significant force, but the force required is much more than that of Superviolet.

The emotional effect of drafting this colour is that Blues are orderly, inquisitive, and unfailingly rational. Structure, rules, and hierarchy are important to Blues.

Green
Arguably the most versatile of all colours, Green is flexible and rubbery. The uses of Green are only as limited by the Drafter's capabilities, as Green can be used to create things such as furniture, projectiles, shields, to springs.

The emotional effect of drafting this colour is that Greens are wild and free; they don't so much disrespect authority as not even recognize it.

Yellow
Yellow Luxin is most often a liquid that releases its energy back into light quickly, allowing its use as a torch or a trigger to ignite flammable materials or explosives. Yellow also has the unique property of nourishing other Luxins, extending their durability, and that particular property makes it a common choice for an auxiliary colour. However, Superchromats (and only Superchromats) are able to draft yellow perfectly; the result is similar to water turning into ice: Yellow Luxin becomes the hardest of all Luxin.

The emotional effect of drafting this colour is that Yellows tend to be clear thinkers, intellect and emotion in perfect balance.

Orange
Orange Luxin is rarely a desirable colour for most Drafters, Orange is slippery and heavy (and as such it is commonly used in conjunction with traps or machines). However, the highly skilled Oranges can create hexes with Orange (constructs that create extreme emotion when a person looks at it; for example, a person might see a hole and not even realise it's there because of the hex making them bored when they so much as gaze at it).

The emotional effect of drafting this colour is that Oranges are often artists, brilliant in understanding other people’s emotions and motivations. Some use this to defy or exceed expectations; others become master manipulators.

Red
Red Luxin is an extremely sticky, gooey liquid that is also extremely flammable. Red is most commonly used with either Fire Magic or the use of Sub-Red Luxin to create bombs. It is common of either a Red to learn to use Sub-Red to enhance their Red Luxin.

The emotional effect of drafting this colour is that Reds are quick tempered, impulsive, lusty, and love destruction.

Sub-Red
Sub-Red is created by the user firstly dilating their pupils so much, to the point where they can see heat, and (to an extent) see in the dark. Sub-Reds draft heat from their surroundings, and turn it into flame crystals, which combust when they come into contact with oxygen. Due to the nature of the Luxin, they will commonly try to gain an auxiliary colour of either Red (due to their advantageous relationship) or Superviolet (due to it being both solid, and invisible to the general populace).

The emotional effect of drafting this colour is that Sub-reds are passionate in all ways, the most purely emotional of all the Drafters.

Black
A mythical Luxin that has only ever once been successfully drafted (and even then, most Drafters nowadays look upon it with doubt, due to it being made in ancient times). The Drafting of Black Luxin was described by its Drafter, the Prism of his time, as "brining Hell to earth", and that it was "madness incarnate". The creator of it also said it "had a mind of its own", but whether this was merely madness or the truth is unknown.

The emotional effect of Black is unknown.

White
A Luxin that is commonly viewed as godlike, White Luxin has never been successfully drafted in the history of this magic. However, people rarely tread upon this concept due to the certainty of breaking the halo among Full Spectrum Polychromes (as they are the only ones besides the Prism who are viewed to be even be able to attempt the creation of White Luxin.

The emotional effect of White is unknown.

Paryl
A colour that only a fraction of Superchromats can see (although all colourblind can see), Paryl is a colour that's very existence is in question by the world.

The emotional effect of drafting this colour is that Pary drafters have an extremely strong sense of empathy towards others.

Dangers and Colour Wights
The most dangerous part of being a Drafter is breaking the halo; this means the drafting of too much in one's lifetime. Over the course of a Drafter's life, their respective Luxin/s will accumulate around their pupils, causing a halo/s of colour to appear around it (if they can draft multiple colours then the sections' size will vary accordingly to how much of each colour they draft). Once the halo reaches the edges of the iris, a person is faced with two possibilities: stop drafting, or continue to draft and break the halo.

The breaking of the halo results in one of two things: they die, or they live. The death will be caused by the person losing control of their own magic, resulting in them turning into Luxin statues. But if they live then they face two possibilities: draft Luxin into their own bodies to gain greater strength (but their emotions are warped into the direction of their colour/s), or gain weaker drafting abilities compared to their past selves, but gain greater insight into the colour/s they draft (if they draft multiple colours then their skill with their auxiliary colours will become equal to their main colour).

If a person is able to successfully draft Luxin into their own bodies then they become what is known a Colour Wight. A Colour Wight is a person who has begun to replace parts of their body with Luxin to enhance their physical abilities; for example a Green might replace their skin with Luxin to give them greater defence, or give themselves new legs to give them greatly enhanced jumping. Another advantage of becoming a Colour Wight is once you draft Luxin into your body you can redraft it into whatever you desire, but doing so is dangerous due to your body possibly needing it to live. Also, the most skilled Colour Wights can change their own organs into Luxin, and as such a Blue may attempt to do this to gain greater survivability (although the reasons for some doing this are plain illogical; for example, a Sub-Red doing this would only kill them).

Due to the emotional effects of becoming a Colour Wight, they are commonly viewed as insane and deranged, when, in actuality, they just have overriding emotions. But due to the dangerous natures of Colour Wights and their emotions, anyone who breaks the halo is viewed as extremely dangerous and should be dealt with accordingly.

Trivia

 * This magic is heavily based off Drafters in the Lightbringer series, although there are some differences (such as a person attaining multiple colours, as a person can only attain this via the latter).
 * Large amounts of thanks must be given to the The Black Prism Wikipedia page, and I borrowed the emotion descriptions from there.
