This is the picture i started with to experiment with colour space whilst in RGB colour.


This is what it looks like when you remove the red channel

This is what it looks like when you remove the green channel

This is what happens when you remove the blue channel

This is what happens if you remove two of the channels

You can only choose the channels red green and blue because they are the three primary colours of light.

A photoshop image is made up of tiny squares called pixels that are one of these three colours

You can see how the squares are coloured differently to make up the colours of the band members face. If you use a colour picker you can see the values of red green and blue which are needed to make up that particular shade as every colour value is a number.

The colour mode which is used for printing is CMYK (cyan, magenta, yellow, key- black)
Because each coloured print needs these four colours in, the image is printed four times.
(change image mode to get to this)
This is the picture without the cyan channel in
