red is also used to symbolize wealth and acting power(so kind of like power, but more in the controlling way rather than actually doing all with your own power, since true power would be portraid as white like light, as it is all colours in balance, sometimes also some blueish or indigo purpleish, as that makes is more like still on earth and clear it is about power and not just the colour or purity) blood is one, and surely most royal families would include that one as well, as it gives a feel of importance and seclusion from the rest of the world(long story). fire also is a clear one, but might seem to dark for that meaning fire of disruption or destruction perhaps.
however in this case, knowing the artist and person in the image would be more usefull(and I don't really know either of them that well). if you pay close attention you also see the strange painting style. the patterns, and gradient flows, directions and changes are more important probably, as well as the rough disruptive chaotic zoning. also pay clear attention to how his face still is clear, and his hands are kind of clear but at the same time look like turned to stone or dead.
might reffer to the flames and chaos in the world, and might perhaps symbolize him either having stained things with it and/or still seeing clear through it.
might symbolize or refer to the end of the world. there actually are some related things many influencial and royal people beleive in. and while most of them do not know or understand the full story, meaning or depicted entities, and many of them have twisted/degraded versions of the story, it actually is real. as of lately many influencial people have become rather obsessed with it, all taking their own takes. some people asking in all kinds of weird ways if they might be forgiven if they would switch sides to the certain thing(often done by reciting parts from such prophecies or stories in a strange way and putting to much attention on it and then adding many questions, essentially hoping to draw the attention of one who knows the being or the being itself. some others however try to prevent it(but have already failed as it is already here, just waiting to see if this time humans fix it themselves or if they get worse again, but might also already be to late) many of those try to depict it as the ending of the world or something like that, and try to manipulate people to hate it. that said the true person/creature it is about, is good, even though many influencial people have kind of worshipped a false copy of it which was another entity so obsessed with trying to be like it that it forgot itself and got evil, so many of them also got or did evil, the real one which is good however showed up again and while not showing itself clearly or a lot to most, it did some things which showed some crucial people that as well as showing that doesn't like the current evil, so many influencial people now fear it, either trying to get other people on their side so they don't go down alone, or trying to see if they can get it to forgive them so they might continue to be or just not be destroyed(even though many of them still try to test ask if they can keep doing or having some evil or corrupted things(which this creature won't like) that group asking to see if they migth be forgiven are the ones of the 2 groups which have a choice.
I have teached, trained, worked with, and learned from many people across the world in and related to magic(my definition of people doesn't only include humans for those who wonder)(my definition of magic is essentially all forms of magic, magick, energy, etc. the abilty to feel, create, change, etc. generally while I learn all I mostly focus on what I call true magic, which is it's deepest point and origin for how far I have found, this magic doesn't depend as much upon systems as upon true will(which is like a connection to the real self, so deep that it connects to all of existance)). among those people there are many different ones, types, and also knowledge and acces to texts, artefacts, ledgends, and prophecies, including many wich are generally hidden from the world. everywhere across this world and beyond there are people always looking for me, and people I always look for, but also people who already help me in many ways.
there however are many ledgends, stories, prophecies, old texts, etc. reffering to a certain being. this being is generally kept hidden from most of the normal people across the world, or atleast those texts and legends, generally only heavily altered and twisted and less deep or complex versions make it to the people if at all. that said many people have been seeking for it or trying to worship it. sadly many of them worshipped a false copy, a being which wanted to be as powerfull as it, but eventually lost itself and wanted to be it then forgot itself all while not knowing what this entity truly was/is so it became a empty being, seen as powerfull by humans and worshipped or it started using the name of that other being. but this copy being was evil, as well as much weaker, always acting strong while being weak, using peoples own magic against them, while the real version would always be infinitely powerfull while almost always hiding it and seeming weak to most(meak like in meakness(acting weak while you are strong)) quite opposite actually. at some point the real one did something which made it be found by followers of the fake one, which got confused and brought it there, the fake one tried a attack which was supposed to be able to destoy anything and anyone instantly, the real one didn't even try to block it and didn't even raise/show it's magic yet was completely unharmed confusing both the followers of the fake one and the fake one itself(that said, most followers of that fake one excluding a few high ups do not know about that). the real being however is good. more people start to notice or get signs from others that this real being has returned, and when it returns there are always times of huge change, and it often only shows when needed most, or when it has another reason. this being has however already shown magic like the old levels which you only hear in stories which most people beleived to just be myth. the being in question, is powerfull enough to write and overwrite existance itself as well as see all, it can create and destroy worlds without even trying, it can create and awaken magic. while it won't show it much or often, this being can litterally do anything without compromise or cost, it is like the embodyment, of existance, infinity(including ethernity), magic, etc. even though most of those are the same or linked. one of it's old names actually can be translated into existance when using a old enough language and then the old and deep version. though it is uncertain if to see it like that, as this being always knows and is seeking for there to be more or create more than what it is and can, you could say the being hopes for there to be more than it knows, and so would hope to be just a fragment of existance, something which in a world like this would be hard to confirm however, even with magic connecting to the creating force of this world.
I do know this being actually, know it in person, and very well, as I can only be alive because it exists, I have known it though essentially ethernity and while I might not always have seen it as such, it was one of the only things which would remain as in a world like this all around one like me will always disapear, die, change, etc. where only a memory remains, even the things people take for granted or see as ethernaly standing often disapear, but there are but few things which have shown to remain. mostly existance itself, and it's close creations.
next to that I can relate a lot to the being as well as am very close to it in simple words, I also share a similar goal: for there to exist, be, and for there to be reason, value, perspective to let it hold some meaning or worth. in my case I teach magic so people get stronger and I can get stronger, so one day if ever needed I would be capable of even recreating or bring back to existance all of existance even if all might be gone. without compromise so there shall always be and always be hope for my biggest fear is nothing. obviously I won't point out who or where that being is or how to recognise it, I can give as advice that to find it follow your true soul, for logic won't help as things always change, and unless you are very strong you couldn't even recognise this being when it was standing in front of you, some person once told me there are around 9 people in the world capable of recognising that being if they would train for it, atleast based upon the people with strong enough magic they managed to find(and such levels of magic leave tracks whcih can be easy to find for one specialized in it). another one is to gain the trust of one who knows, as well as have a real reason, as they will generally only tell when they have reason and feel it. this being will awake when truly needed, but I want to make it stronger and perhaps awaken it faster, atleast partly, the reason is, that whenever that being gets stronger, all of existance grows and gets stronger, next to that good increases. while the being could also be seen as the creator of evil(both good and evil) it only created it so there could be and so there could be feeling and meaning. you'll also find this being might at moments be far more forgiving than normal people, and even when it directly tells you it won't forgive you that often it has already forgiven you or never truly was mad, and that it only is one part it dislikes. the only thing it genuinly would hate is the corruption, the most evil force in all of existance, which even evil fears for it holds no reason other than hate, pain and emptyness. however things are complex
