Red/Green/Blue Channels Splitter
Answers to Questions (FAQ)
What are RGB channels in an image? (Definition)
RGB channels result from a decomposition of an image into components of primary colors. There are 3 primary colors: Red, Green and Blue, also called RGB colors.
How to separate RGB values of an image?
The image will be analyzed and the result will be returned in gray level for each color, from black to white, from no color to pure color.
Example: Red 
Example: Green 
Example: Blue 
The image will be resized if it is too large to accelerate calculations.
Thus, in an image encoded in RGB, the white color corresponds to the presence of the three colors simultaneously. The black color corresponds to an absence of three colors simultaneously.
Why using RGB channels?
The red, green and blue elements are the best hues captured by the human eye.
What is the relation between RGB and HTML color codes?
The HTML color codes consist of 3 hexadecimal numbers corresponding to the 3 RGB colors.
Example: #ff7f00 for ff,7f,00 is ff for red, 7f for green and 00 for blue
