Colors

Colors and Life!

Hi, this is Sultan! I saw something on television the other day, I thought you'd enjoy hearing about it.It was a report on color, color changes how you feel. Scientists say red makes you hungry that's why many restaurants have red walls. They also say pink makes you calm, pink rooms help you relax. If this is true do you think colors change the way you feel? Here is some Information about color, it is quite amazing and has changed my life! A bright color can make you feel happy where as a dull color can make you feel sad.Your personality color tells you a lot about yourself, how you function and how others see you. It is the means to understanding your. I'm not an expert, but I think I'm going to understand something, "what is color?".



What is Color?

Light is a kind of energy that can travel through space. Light from the sun or a light bulb looks white, but it is really a mixture of many colors.

The colors in white light are red, orange, yellow, green, blue and violet. Color is light you can see and comes in seven wavelength groups. When the light hits an object, the wavelengths are absorbed and reflected back to what we see as color.

How we see color?

The human eye and brain together translate light into color. Light receptors within the eye transmit messages to the brain, which produces the familiar sensations of color.Through the eye, we can see darkness, brightness and different colors.The ability to see color depends on the many complicated workings of the eyes and brain. When we look at an object, light coming from the object enters our eyes. Each eye focuses the light, which forms an image of the object on the retina. The retina is a thin layer of tissue covering the back and sides of the inside of the eyeball. It contains millions of light-sensitive cells. These cells absorb most of the light that falls on the retina and convert the light to electrical signals. These electrical signals then travel through nerves which lead to the brain. When we observe a red ball is that the ball appears red because it reflects only red light and absorbs all other light. The ball does not have color in itself. The light generates the color. What we see as color is the reflection of specific wavelength of light rays off an object.The color white: If all light waves are reflected from a surface the surface will appear to be white. The color black: Similarly, when all light waves are absorbed by a surface the surface will appear to be black. The energy of light waves is converted into heat when absorbed. Wearing white or light colored clothing during hot summer days takes advantage of the quality. When you ask children to tell you the names of all the colors, they'll know red, blue, yellow and a few more. A basic color wheel, it is based on 3 different types of colors: primary, secondary, and tertiary.






1.Primary Colors

Red, Yellow, Blue These are colors that cannot be created through the mixing of other colors. They are colors in their own right. The three primary colors are RED - YELLOW - BLUE.

2.Secondary Colors






Green, orange and purplePrimary colors can be mixed together to produce SECONDARY COLORS or Secondary colors are formed by mixing 2 primary colors. Primary Colors cannot be created by mixing other colors and (Primary colors) can be combined to produce any color in the rainbow! Primary as in the Basic First colors to form other colors. Red, Blue and Yellow are considered "Primary" colors. You can use red and blue to make a color, yellow and blue to make a color and yellow and red to make a color. They are called "Secondary Colors." This is the idea of "Color Theory."Proper use of basic color theory can help you decide what colors match, as well as what each color makes people feel.




Sir Isaac Newton developed the first circular diagram of colors in 1666. Since then scientists and artists have studied and designed numerous variations of this concept.

3.Tertiary Colors

Tertiary colors are combinations of primary and secondary colours. Tertairy colors consiste of red-orange, yellow-orange, yellow-green, blue-green, blue-violet, and red-violet. Tertiary colors are formed by mixing primary and secondary colors, resulting in the two-word names. (Cyan, Magenta, Yellow, Black) Many computer printers and traditional "four-color" You can't mix colors to get black and white, black and white are colors that you need to start out with. If you mix a bunch of colors together you might get a dark brown, but not black. Ink and paint get their colors by absorbing some of the colors in white light and reflecting others. Green ink looks green because it reflects the green part of white light and absorbs all the other colors. Red ink looks red because it reflects red light and absorbs all the other colors. When you mix green, red, blue, and yellow ink, each ink that you add absorbs more light. That leaves less light to reflect to your eye. Since the mixture absorbs light of many colors and reflects very little, you end up with black.

What does your personality color say about you and how do colors affect us?

Different cultures have different meanings for colors, what do the different colors mean in your culture?
