Unknown Story

Hi, I've been doing some research on digital technologies and was wondering if you could help me?
Of course! What do you need help with?
I was hoping you could help me understand images and how they are displayed using pixels.
Well, digital technologies consist of lots of different parts. One of them is pixels. Pixels are the small squares of colour that make up an image. Each pixel has its own unique number sequence known as binary numbers. Each binary number has its own binary value.
What are 'Binary values and binary numbers?'
Binary numbers are a combination of numbers made up of only 1's and 0's. Binary values are the sequences of 1's and 0's that represent numbers.
Oh cool! But how are the pixels coloured? What determines their colour?
That would be the RGB's in each pixel. There are three RGB colours; Red, Green and Blue. That's what RGB stands for. For every colour each pixel displays it's own RGB value. RGB values range from 0 - 255.
But how do the RGB's make all different colours if there are only three colours?
By combining, When the pixel's value is at 0 each LED is off which means that the colour appears black. When the pixel's value is at 255 the LED is fully on so the colour appears white. This allows each colour to change its' LED to make different colour combinations.
Thank-you for helping me, this makes much more sense now!
Of course I was glad to help.
