Color models RGB & CMY: If you are designing anything using colors, you should be familiar with the two most basic and well-known color models: RGB and CMY. For most purposes, what you really should be interested in is that RGB color is used for digital communication, like televisions or websites and CMY is used for printing. • RGB stands for the colors red, green, and blue, the colors widely recognized in design fields as the primary colors. It is also an additive type of color models. All colors begin with black or what is called “Darkness”, and as you add more lights of colors to it, it becomes white which is seen or visible to the eye (all colors shining together like a light bulb). RGB maxes at the color white, which is the same as having all colors added together with full brightness. • CMY is a subtractive type of a color model, just like paint/pigment. Everything begins with nothing, just a white paper and as you add more colors, at the end it turns black. CMY represents the standard colored inks used in printers to create different colors like cyan, magenta, yellow and black. If you happen to be watching something on TV, for example watching a movie. In that case you are using RGB. That is how monitors like cameras and televisions display colors. On the other hand CMY is not something you need to be worrying about while …show more content…
In the RGB the computer monitor works on mixing the colors red, green and blue to create colorful pictures. On the other hand, the CMYK color model, uses absorbing lights inks, cyan, magenta and yellow, whose colors are mixed using half toning. The items which are displayed on any type of monitors like a computer monitor, might not match the items which are printed if the opposite color modes are combined in the two
Guillermo Gonzalez Camarena invented color television at the age of 17. In order to make more money to continue his investigative work,he wrote many songs , but it was “Río Colorado” that became a huge hit and provided the funds for him to move forward with his engineering work. Guillermo’s invention benefit the world because now we can have channels in colors, and not just in black and white. He gave us
The lab experiment did prove that Crayola colors are not of pure substances but rather a mixture of specific color compounds needed to produce said colors. The experiment also proved that different color pigments have different densities (the lighter ones moved up the filter paper with the water, while the heavier ones adhered to the filter paper longer.)
The three colors that are most widely used during the movie to show symbolism and imagery are black, white, and red. While there are some references to color in the written text of Titus Andronicus, Taymor’s use of color allows the viewer to see a more clear representation of mood, tone, and character. Colors may be used in costume or in setting. Regardless of how they are used, each color plays a large role in distinguishing the tone that is being set for a scene or character. The first color that is widely used is black.
These devices are attached to the motherboard through different connections. The output devices like monitors and printers can be used by a file server to show different files or print hard copies of files. These devices take the data from the computer and put it into a format that users can read and understand. I would like to take a moment here and go over the different kinds of monitors that a person can use as an output device. The first is the regular CRT monitors are heavy and use a lot of electric power to display objects, but are preferred by graphical artist for the color rendition. Then there are the flat panel monitors, which can use liquid Crystal Display (LCD) or a plasma display. These displays use electronically at each pixel to control the color. The input devices like a keyboards and a mouse. These inputs take the movements from the users and turn it into data that the computer can understand. (Beach,
Red is by far the most used color in this book. It is used so much because it has so many meanings. The color red is interchangeable with the colors crimson, ruby, blood, and rose. Red comes in various shades too, but with each different shade comes a different meaning. There is light red, pink, dark red, and
The vibrant use of colors is meant to express the environmental conditions, as well as the character’s emotions. The main color during the whole film is red. The film uses red, yellow and orange to show me and keep reminding me about the heat. There is a scene in the film where three men sit against this bright red wall, and this shot isn 't just shown once in the film but multiple times. Even though the bright sun is never shown, I can tell how hot it is because of the colors. It also uses red to convey the character’s emotions such as anger, struggle, dissatisfaction, and frustration. For example, Jade’s apartment is red color to show Jade is a frustrated character in the film. It’s as though; colors were characters in the movie
Since hundred years ago, when people started to make maps to show distinct regions, such as states or countries, the four color theorem has been well known among many mapmakers. Because a mapmaker who can plan very well, will only need four colors to color the map that he makes. The basic rule of coloring a map is that if two regions are next to each other, the mapmaker has to use two different colors to color the adjacent regions. The reason is because when two regions share one boundary can never be the same color. Another basic rule of coloring a map is that if two regions share only one point, then they do not necessary have to be colored differently. Many evidence showed that coloring a map required at least four colors but no more than five. Then mathematicians started to asked questions, such as “ Is it true that using only four colors are enough? Is there any exception that one has to color a map that requires more than four colors? Or is it has to do with a special sequence of arrangement that involved with different regions in order to make the theorem true?” However, the first mathmatician who asked these questions is a man named Francis Guthrie. He was the first one who posed the four color problem in1852.
Modern colour LCD screens work on a similar principle to monochrome LCD screen, the main difference is the configuration of the pixels and the source of the light. One pixel on an LCD screen is made of 3 sub pixels each of which is a primary colour but each sub pixel is activated by current passing through the through an electrode and changing properties of the liquid crystal. This type of LCD screen is made up of 7 layers the first of which is a fluorescent backlight differing from the mirror on the basic LCD, this allows for the screen to appear bright and to been seen well in a dark room. The screen consists of a mirror then a layer of polarized Film, a layer of liquid Crystals sandwiched between a positive and negative electrode/glass, another layer of polarised Film set perpendicular to the other piece of ...
While LCDs also create pictures by lighting up red, green and yellow pixels, the ...
We took pictures of each other’s data once finished with the lab. For the paper chromatography, students began by grinding 5g of spinach along with 2g of anhydrous magnesium sulfate. Students added hexanes and acetone as specified by the lab protocols. Once, the solvent was a dark green color, we placed it in a centrifuge and transfer the liquid portion of the solution into a test tube. Throughout this portion of the experiment, students used weighting paper as a funnel poring the indicated solution as stated by the protocol, for instance pouring silica gel and sand into the column. After, we poured about 3ml of Hexanes into the column, making sure not to let the column dry. We then added, spinach extract to the column—after, we added about 1ml of hexanes. Adding hexanes caused the solution to gain a yellow colored band. We added hexanes until the yellow band reached the bottom of the column, thus began to collect all the yellow pigment into a test tube. Once the elutant become colorless, we once again placed a waste basket under it. Finally, we collected the green pigment into another test tube by a 70%/ 30% mixture and a bit of acetone. Once the two colored bands were collected, we obtained the wavelengths of each colored band using the
To identify inks of similar color from one another from mere observation is near impossible since colors can look identical to the human eye while differing in composition. Therefor, further examination of the components of the ink is needed. Ink is a mixture of substances and these substances have varying molecular polarities. The intrinsic properties of the components of the ink allows for the separation of ink through adsorption chromatography, where the ink is separated based on the attraction to a moving phase (liquid) and stationary phase (TLC plate). Using the Rf equation, the Rf value can be determine to numerically determine the similarity in the inks
An advantage of being colorblind is being able to detect camouflage. “During World War II, colorblind servicemen reportedly spotted hidden enemy soldiers.” It is easier to see camo when you are colorblind because you see the outlines of patterns, but not the actual colors. This makes it easy to help out in wars and to detect enemies, ships, tanks, and weaponry that

...roprietary colour specification systems such as PANTONE and COLORCURVE. These vendors are likely to give their colour specification systems in a small form to plug into colour managers.” The topic of what white and black is has always been a challenge. We know that white means no color and black means all colors in the visible spectrum. “In additive image reproduction, the white point is the chromaticity of the colour reproduced by equal red, green and blue components. White point is a function of the point of power in the primaries.” ( BW Tek 2011)
