The principle of color in multimedia

Que-1. Explain the principle of color in multimedia. How many dimensions are used in the color? Explain with suitable example.



Color helps make the foreground/background distinction. Light color indicates background while bold colors indicate fore ground.

Avoid strong backgrounds. They put the background “in your face” and de-emphasize texts and graphics which need to be in the foreground.

Limit your pallet to 3 or 4 colors. Like fonts, too many colorswill be distracting.

Some colors have inherent meaning.

•Blue = comfort, “clear, blue sky”

•Green = growth, “lush, green forest”

•Red = danger, fire & red light

•Blue is for baby boys.

•Pink is for baby girls.

Dimension of a color

Intensity: The brightness or dullness of a color.

Value: The lightness or darkness of a color.

Hue: the color sensation associated with different parts of the spectrum such as red, yellow, or blue.


Shade: Made by adding black to a color so that it is darker.


2. How an appearance of an image on a monitor is depend on monitor resolution and monitor size?

Ans2. The dimensions of your image on screen will often be very different to the size of the original you are scanning in. The size of the image on screen depends on monitor resolution and monitor size.

o Video cards are able to display a particular set number of pixels horizontally and vertically on the screen. For example, the card may display (width and height ) 640 x 480 pixels or 800 x 600 pixels. For more information on the different display settings .

o Physical dimension of the monitor. A large monitor set to 640 x 480 pixels uses larger pixels than a small monitor with the same setting.

· Popular video screen size settings are:

* 640x480 or 800x600 pixels for 14 inch monitors

* 800x600 or 1024x768 pixels for 15 inch monitors

* 1024x768 or 1152x864 pixels for 17 inch monitors

· 1152x864 or 1280x1024 pixels for 19 inch monitors

Q3. Discuss the physical and psychological principles as to why animation works, as well as how it is Usually presented


The 12 principles

Squash and stretch


Straight ahead action and pose to pose

Follow through and overlapping action

Slow in and slow out



Secondary action




Solid drawing


Psychological: Noticing it or not, people express feelings and thoughts through (secondary) actions while trying to do what they need to (primary, main actions). While the latter can be direct consequences of someone's decisions earlier in the story, the secondary movements are able to give an immediate account of how a person feels at a given moment and, judging more carefully, what kind of personality she probably has.


Facial expressions naturally play a crucial part in defining what a character feels, unless when trying to hide it. There are many different signs a character can expose while talking or doing anything else. Head tilts and eye blinking are also effective tools for expression.

•Imagine someone walking, a normal healthy and determined walk, no hint about feelings or thoughts. That's the main action.

Q4. What are the different color models? What is the need to use different color models?


The need to use different color models is that all of these color models--and more--are widely used to describe colors, both by software and by various types of hardware like digital cameras, scanners, monitors, and printers. Unfortunately, most of these have historically been device-dependent models -- meaning that the designation for a given color applies only to the particular device. And that makes it hard to move color information between devices without introducing errors.

RGB is a device-dependent color space: different devices detect or reproduce a given RGB value differently, since the color elements (such as phosphors or dyes) and their response to the individual R, G, and B levels vary from manufacturer to manufacturer, or even in the same device over time. Thus an RGB value does not define the same color across devices without some kind of color management.

Q5. What advantages does the computer provide over traditional animation practices?


* Reproduction of some works of art, which were destroyed by natural reasons or by men.

* Producing events which require high costs and events which can cause danger like explosion and collision.

* Creating some products through computer that have not been produced yet.

* Producing moving images generated from graphical materials like photograph, letter font, figure, schema, map.

* Transforming complex events into basic graphical expressions.

Transforming the abstract thoughts into concrete images

Q6. Discuss where and how you might use animation in one of the following project? Be creative. How could it best be used to visually illustrate a concept?


Using flash player we can display our products.

* We can display our new updates through this interface.

* Video contents will be displayed through any player.

* by using animation we can display pictures

* By using flash player we can display video contents

* Research work will be displayed through animation

All pictures can also be displayed using banner shop software
