Primary Colors

[Derek]

Simple question - What are the 3 primary colors?

[Lorne]

Depends. There are additive, subtractive, and biological answers to that (and the latter depends on the organism you're talking about, technically).

i always use Red, Green and blue as primary... as i have been learned :) (RGB)

[Desmond]

I still think of mixing finger paints in preschool ... Red, Blue, Yellow.

[Derek]

So, in fact ... not a simple question!

When you are talking about Light, RGB are the Primary colors (R+G+B = White. no R + no G + no B = Black).
In the printing business, primary colors are CMYK (Cyan, Magenta, Yellow, Black). All of them give you Black...well, actually, a "dirty" black. None of them is white (white paper before printing).
A full color screen image is, usually 24 bits, or 8 bits Red, 8 bits Green, 8 bits Blue.
8 bits means 2 to the power of 8 (2X2X2X2X2X2X2X2 = 256). That is the basis of 0 to 255 values for each of these colors. So 24 bits means a Total number of colors of 256X256X256 = 2**8 X 2**8 X 2**8 = 2**24 = 16,777,216.

Higher end images can use 16 bits or more (16 bits channels in Photoshop...), meaning 65,536 values for each color (RGB) instead of 256.

Hope that helps

They're called links. Amazing things. Clicking on them leads to pages with information on them. Sometimes there are even detailed answers to questions and stuff! :)

Yeah, but the question is: Who is "they"?

[Derek]

Yeah, but the question is: Who is "they"?
You've never heard of The They Group ? :wow

I only posted the question to see what kind of response it got.

The day before i posted it i got into a discussion at work about it and, until i looked into it, i never realised there were so many 'sets' of primary colors. So doesn't that make the term 'primary' null and void?

For the Human Eye Primary Colors are RGB Red Green and Blue but the eye correct automatic mode the ligths and shadows adjusting the size off the inner eye

for printing primary colors are CYMK Cian Yellow Magenta and Black

to add ligths we will use the witthe paper and for adding shadows will use the black ink

in printers who use only 3 inks the black will be created with saturation off all 3 inks

i add an CYMK scale hope this get u at the rigth direction
