As described in Color-Affects.co.uk, there are 4 main colors that affect our daily psychology, namely red, blue, yellow, and green. They are related to the body, mind, emotions, and important balance between the three. Green color means balance. He has positive benefits for us, such as bringing harmony in everyday life, emotional balance, refreshment of the eyes and mind, soothing, making us care about the environment, balance of mind, and bring peace. However, green color also has "side effects" such as can make us feel bored, it feels so-so, make us weak and weak. When the eyes see something green or green, our eyes do not need any adjustment, so we feel comfortable and calm when looking at it. When we see the color green, we will feel the presence of nature, such as the presence of water, and feel safe because the sense of danger threats less. Green is considered a soothing and relaxing color, perfect for people who are tense or need to balance emotions and create an openness between you and others.
Green is also associated with the heart chakra, so this color is believed to help emotional problems, such as love, trust, and affection. The researchers found also that green color can improve reading ability for students. Those who used to read material on transparent green sheets will increase the speed of reading and understanding. Perhaps because of the effect of this green color is to relax and calm our mind. So, at least we know that the effect or benefit of seeing green is more than just 'refreshing' the eye. Although maybe the eyes will not be healthier after seeing the color green, at least the mind so quieter.
