Now that's one hell of a MIND JOB, right there!!! Thank you!!!

Very, very, very well stated. Made it simple enough that I assume a 6th grader would know what's up. But detailed enough to start a conversation =D

@pepnacho65 Here's some math ahead: properly converting a color image to grayscale takes advantage of the fact that human eyes are more sensitive to green than blue and red.
To get the grayscale value you compute the dot product of the original color and 0.3, 0.59, 0.11 representing the three colors in a 3-float vector. In other words, green gets the most weight and blue gets the least. Those three numbers are approximate values.

@pepenacho65 The reason green is used more and in fact the reason those three colors are chosen actually relates more to the structure of a human eye. They have cone cells that are like the "sensels" our eyes and well they react best to those colors. So we are just following what is already part of our anatomy.
The cells that respond to green light are the most sensitive so electronic displays tend to use more components for green colors.

You said it was 256 each but in photoshop its 255, why?

@G3org3Master because it starts at 0, not 1.

yellow is red + green? yellow is a prime colour. yellow + blue make green but yellow can not be made by mixing 2 colours

@robertwc82 You are thinking about CMYK, not RGB

@MichaelTheMentor CMYK?
robertwc82 1 year ago
@robertwc82 Yes, Y is a primary color in the CMYK color model -(Cyan, Magenta, Yellow and Key, which is Black) It is used primarily for printing. Very easy to see where the confusion comes in. The recording of light on a digital sensor in most cases is using RGB as described on the video.
