White
White wants peace.
White looks around and sees a world of suffering. There are so many individuals that struggle day to day, but the world has the resources to address this suffering. There is enough for everyone to have what they need (as opposed to what they want). Suffering is a by-product of individuals not prioritizing the good of the group.
White wants to create a world where there is no unnecessary suffering, a world where life is as good as it can be for each individual. The key to making this happen is teaching individuals the importance of taking actions which benefit the group as a whole, even if those actions might not benefit them personally.
The problem with this plan is it can only succeed if everyone is working toward the same unified goal. As soon as some individuals prioritize other things, like say their own desires, the plan falls apart. This means that white has to work extra hard to get the group to understand the power it holds and to keep the focus on the bigger picture.
White does want as many as possible to understand its motives and share them. But white realizes that in order to accomplish its larger goal, some individuals will have to be lead down the path rather than venture there of their own accord.
Blue
Blue wants perfection.
Blue believes that each and every one of us is born a blank slate with the potential to become anything. The entire point of life is figuring out what you could achieve with the right education, experience, and tools. Note that this is not a task with an end goal, but one that continues throughout your life. There will always be things you can do to improve, change, or adapt. The journey of life is one of constant discovery as you keep seeking to better yourself.
In order for individuals to do this, there has to be a society that accepts and encourages this behavior. Opportunities for education are vital. Places to experience things through trial and error are mandatory. Access to the top-of-the-line tools needs to be a right of every citizen.
In addition, this way of living requires the right attitude. You have to be open to possibilities, but also not too hasty in action. Blue recognizes that there are many forces, even some that come from within, that lead an individual astray. Time is a valuable resource because only with time can one get the things they need to improve. This means that individuals need to be careful and deliberate in all their decision making. It is better to think one's options out carefully and select correctly, than to rush to a decision.
Blue is methodical and exact. Because when one sets out to become the best individual they can be, one doesn't have the luxury of making mistakes. Well, not unless they occur within a controlled environment.
Much as blue wishes to perfect itself, it also wants to perfect the world it lives in. Part of this is to ensure that blue has access to the resources it needs, but part of it is the belief that an element of reaching one's potential is living within a world that has reached its own potential. As such, blue is the color most interested in technology and wants the latest and greatest version of whatever it is using.
Black
Black wants power.
Black looks at all the other colors and feels that each of them sees the world as they wish it to be. Black is the only realist, the only color to look and see the world as it is. An individual is free to have whatever they want, provided they have the power to obtain and keep it. This makes power the most important resource, because it's the one thing that can guarantee your ability to control your life and thus your happiness.
It's important for everyone to understand that black didn't make the world greedy. The world was already greedy; black has just learned how to thrive within it. Black has two big things on its side. One, it understands and accepts the system better than anyone else. And two, black doesn't place any restrictions on itself that make its success more difficult.
Black's philosophy is very simple: There's no one better suited to look after your own interests than you. Therefore, if everyone looks out after their own interests, you've created a system where everyone has someone looking out for them. In addition, black's system allows everyone the opportunity to succeed. Will everyone succeed? Of course not—but once again, that's not black's doing. That's just how the world works.
The weak will fail. That's what makes them the weak. Doing anything to help them is both prolonging the inevitable and risking failing alongside them. It's not personal to black. Black does what it needs to do to succeed. If others can't do the same, well, then they deserve their fate. Others see this as black being heartless, but black realizes it's just being pragmatic.
There will always be those who suffer. Once again, this isn't black's doing. It's an inevitability of life. Black's just the one color that owns up to the truth and acts accordingly.
Red
Red wants freedom.
Everyone seems preoccupied with the meaning of life. Red's not, because red already knows the answer. You see, your heart tells you what it needs in order to be fulfilled. All you have to do is listen to it and act accordingly. It's not a mystery. You are literally bombarded with constant feelings that guide you down the correct path. The problem is all the other colors ignore the message.
Life's an adventure, and it's up to each individual to experience it. The key is to embrace your emotions and let them guide you. If you're happy, laugh. If you're sad, cry. If you're angry, hit something. If you're scared, run away. Listen to your inner voice and you will have the opportunity to experience all that life has to offer.
Too many individuals live their life questioning choices they've made. Not red. Red lives in the moment; red is spontaneous; red embraces every adventure put before it. Red knows that on its deathbed, it will look back on a fulfilled life with no regrets. That's all red wants—the ability to live life doing what it needs to.
This doesn't mean red is alone. Quite the opposite actually. Part of living life is embracing relationships. Red knows passion and loyalty and camaraderie and lust. When red bonds with another, it bonds strongly and fiercely. Whether a lover or a friend, red is someone who will always be there when you need them. Well, unless, life has taken them somewhere else for some length of time—but then when they get back, they're definitely going to be there for you.
To outsiders, red might seem a bit chaotic; but that's only because others can't see what's in red's heart. They cannot feel red's emotions guiding them. Living life to its fullest takes a lot of dedication and perseverance, but red is always up to the task.
Green
Green wants acceptance.
The other colors are all focused on how they'd change the world to make it better. Green is the one color that doesn't want to change the world, because green is convinced that the world already got everything right. The natural order is a thing of beauty and has all the answers to life's problems. The key is learning to sit back and recognize what is right in front of you.
Each individual is born with all the potential they need. The secret to a happy life is to recognize the role you were born into and then embrace it. Do what you were destined to do. The world is this elaborate system, and each one of us gets to play a part. And it's not something we have to guess about; it's imprinted on us, it's in our genes. Just look within.
In addition, you have to learn how you fit into the larger picture. Nature has a beautiful structure. Part of life is recognizing what role you play and how that role interconnects with the web of life. You're not alone. You're part of a complex system full of interdependencies.
The problem is there's so much going on that it's easy to lose track of what's already there. Too many individuals get so caught up in the details of their lives that they don't bother to sit back and understand the bigger picture. Green truly believes that the rest of the colors simply aren't taking the time to appreciate what is already there.
