Colours? Light? Pigment?

[Soquili]

Trying to re-activate some old unused neurons http://www.talkgraphics.com/images/smilies/rolleyes.gif

Seeing the posts about CMYK and RGB, printers and Commercial Printers, monitors and calibration. I decided to try and recall all the things that teachers and professors have attempted to put into my head http://www.talkgraphics.com/images/smilies/eek.gif about colour.

Leaving all the Physics out of it. Frequencies and wavelengths require too much math. This left the fun classes, Art and Photography. Art dealt mostly with pigments; red, yellow, and blue. Photography dealt mostly with light; red, green, and blue. Mrs. Penkowsky would be proud, I think I got them right http://www.talkgraphics.com/images/smilies/biggrin.gif

I always got confused about the additive and subtractive more than which were the primaries for the two. I did remember that white is the presence of all colours and that black was the absence of all colours. I thought maybe if I can do something in XaraX, it would help me visualize which is which better.

So after a bit of playing around and some google searches to get some information (can't rely on the decreasing memory), I made the following image.

A poll some time back (can't remember when http://www.talkgraphics.com/images/smilies/frown.gif) showed that a lot of members are about my age, so I thought I would share http://www.talkgraphics.com/images/smilies/wink.gif
