This webpage uses a different texture than the first example, looking like a math notebook.
The color may even be the most important element of a design, because it offers the most powerful visual impact at a single glance. Color is obvious and does not need basic graphic skills to be noticed.
While lines and shapes mean the same thing as in the reality, only at a little more profound level, the color means exactly the same thing as in the nature. Color creates emotions – red is passionate, blue is calm, green is natural. Even if you don’t realize this, colors have a clear effect on your mind. Studies have been done and a person who lives in a red environment has a higher heartbeat and pulse than a person living in a blue environment. The human brain sees this and influences the rest of the body.
Therefore color theory is very important to know, because not many designers can call themselves experts in this field. Being a master of colors might make the difference between a good design and a stunning one. I am not saying you have to know all of them, but knowing how hue, saturation, shade, tint, tone or chroma work together is crucial for a graphic designer.
