You may not know it, but every single object that you can see on your screen is made up of tiny square ( Or in the case of widescreen desktops, rectangular ) things called pixels.

If you look close enough, you might be able to see these pixels. They will appear to you as a block of Red, Green, Blue.

These colors ( RGB ) are the bane of pixels and colors. Using a scale of 0-255 for each value, you can create any color with this.

With that in mind, to display colors, these pixels shift the values for each pixel to create the color you see on screen.

For instance, if there is a black screen, the pixels on the screen would have an RGB value of 0,0,0.

Pixels are organized in a grid. You might think of a grid as something to plot out lines on for math, but in this case, this is a grid with thousands and thousands of squares ( or, again, rectangles ) to tiny to see unless you look very closely.

Each spot on this grid is filled with a pixel. The pixel is filled with 3 colors. This is how colors and pictures are made on the computer screen.

Pixels can be magical as well. With advancing technology, there came out a software with the ability to use Pixel Shaders. These shaders allow each pixel to come up with a variety of effects, to create interesting results.

Resolutions are based on the number of pixels high and wide your computers screen is. For instance, a computer with the height of 800 pixels and a width of 600 pixels with have the resolution of 800×600, and would contain a total of  480,000 pixels. Each pixel has 3 colors in it, coming to a total of  1,440,000 colors on your screen.

With this in mind, the more pixels you have on your screen, the high resolution, and the clearer the picture will look. A 800×600 picture will be lower quality than a 1480×1260 computer screen.

Pixels are also used outside of computers. Televisions are the most known, but cameras also use pictures to display the images, and they measure the camera scope size in pixels.

So there you go. A basic overview on pixels, resolution, and colors. Now you know!
