What does it really mean to communicate?

...

Body language and social networks.

In today’s world, where technology takes an important role in every human being’s life, communication can also happen through social networks.

Here are some examples:

- Snapchat. In this app you can show your everyday mood and the way you feel about certain topics. It allows you to take photos and videos available to your friends only for 24 hours, making the communication fast and consistent.

- Instagram. In this app you can post photos in which you can show who you are and what you like to do. It’s an inside into your usual activities, friends, food, likes and dislikes, amongst other classic traits of communication.

- Facebook. This app is perhaps the greatest app for communicating with others. It even has a chat that allows you to talk to your friends no matter where they are and to share your emotions via emoticons.

Communication through colors.

Ever wondered why McDonald's colors are red and yellow? You might think that it is only because of their brand or something. But you will be surprised by the truth. Red and yellow form an involuntary orange color in your mind which makes you feel hungry and makes you believe that you will be pleased by eating there. Impressive right? Well that's kind of the whole point in this subject. Let's see that closer.

Let's get scientific. Color is light, which travels to us in waves from the sun, on the same electro-magnetic spectrum as radio and television waves, microwaves, x-rays etc. Light is the only part of the spectrum that we can see, which perhaps explains why we take it less seriously than the invisible power of the other rays. Sir Isaac Newton demonstrated that light travels in waves, when he shone white light through a triangular prism and, when the different wavelengths of light refracted at different angles, he was able to demonstrate that the colors of the rainbow (the spectrum) are the component parts of light.

When light strikes any colored object, the object will absorb only the wavelengths that exactly match its own atomic structure and reflect the rest - which is what we see. Turn this around and it is easy to understand how the color of anything is a clear indication of its atomic structure or, in simple terms, what it is made of. When light strikes the human eye, the wavelengths do so in different ways, influencing our perceptions. In the retina, they are converted into electrical impulses that pass to the hypothalamus, the part of the brain governing our hormones and our endocrine system.

That's why it’s no secret that color has an effect on us. Certain colors evoke certain feelings in individuals and companies and organizations have long since worked to optimize color for their intended purposes. Hospitals decorate in muted shades of pink, green, and blue to bring a calming effect on patients. Advertisers use red in logos to signify power and energy. Manufacturers of baby products attract us with their soft color schemes. So, yes, color communicates.

You can read a lot about color theory and its impact on people, but I might get into a lot of theory and thinking. That's why I'll just leave it like this.
