Exactly why you need to stop condescending me and start understanding me. I know more about the human mind and the Universe than you are comfortable in admitting. If you think frequencies are some sort of mystical jumbo, you really need to reconsider your statements, unless you want to be wrong:
The brain and the heart exist on frequencies; the heart is a stronger brain than the "brain", as the electromagnetic signals are the strongest. These signals carry our emotions, which is why we can tell someone is looking at us from behind; we do not see with our "eyes", we see with electromagnetic waves. Plants communicate in the same way. Birds migrate according to these electrical currents that are invisible to the human eye, except the Northern Lights. That is why a blind man can use the ability of a bat by seeing things in their head, without having a picture in reality. The human eyes can emit "gamma rays", which are the highest frequency of the Universe, as it can produce X-Ray vision under certain conditions. The reason why humans cannot see in X-Ray vision is because the gamma rays are not for us - they are complimenting a part of our eye-sight, but not the conscious sight we use to see the world with.
There are five stages to the frequency: Gamma, Beta, Alpha, Theta (default) and Delta. If you ever feel sleepy and feel yourself getting deeper inside yourself by the second, you're entering "Delta". You can even prove to yourself the slight change of frequency by listening to music while awake, and listening to the same music while half-asleep, you'll notice the sounds are awkwardly arranged in Delta compared to Theta.
These frequencies can either be 100% white when outside of radio-wave signals, or they can be the colors of the rainbow while in radio-wave signals. These colors are the personalities of the Universe, hence why they never change and why they are a great way of experiencing emotion. We don't only "see" colors", we "live through" colors. Our entire imagination is using colors, shapes and patterns as a language underneath our socially conformed language. The blind still can "feel" colors"; they do not have to "see" them. The electromagnetic shield that surrounds our body changes colors depending on our mood and which thoughts we focus on. The Universe is able to make us "feel" electromagnetic pulses in relation to the things which are reacted to, thus why we have a "gut" feeling, which is to say that the Universe, indeed, has a "right/wrong" system underneath our man-made morals already. Even the brain is designed specifically not to kill our own species, unless that part of the brain is "dulled" out. For some reason, the Universe allowed us to "stop using" parts of our brain, which is why people are missing parts; it's because they let go of it, as it did not "benefit" their focuses in life.
These colors also come in the same pattern as the Earth we live on. Red, orange and yellow are the colors of inside this planet. Green, blue and dark blue are the forest and the sea/ocean outside of this planet's core. Purple is the Universe which encompasses it all. And finally, if you add red + blue, you get purple, which is proof this entire Universe is a design based on frequencies, energies, colors and vibrations that are invisible on a physical level.
