Colour Mixing (using paint medium)
artt...@hotmail.com
have been discussing the three primary system of mixing colours on
another forum. This system is still being taught as the gospel by art
teachers however it has been scientifically disproved, is outdated and
does not work! People tell me it works yet I find it hard to find any
one who uses just three colours, 1 x red, 1 x blue, 1 x yellow to make
all the other colours that they need for their work? The best system I
have seen and use myself uses a limited palette of 6 - 8 colours to mix
virtually every colour and hue I need, with very limited exceptions.
All feedback is welcome.

the short answer: yes, artists don't use just three primaries.
The long answer (in this forum):

Den ¿Why do you think it is "scientifically disaproved"? ¿Why do you
think what is "cientifically disparoved" are bad?
Art is older than science. Art crafters created their own practical
knowledge. Color science creates a field where you can see the
differents ways to see the world. What is reality? ¿What "scientifical
instruments" measure? ¿Or what you see?
Science cannot measure your color impression, only the physic data.
Science say you need at least 3 colors, but practical painting teach
you that with 3 colors you have not enought. Think in this: color does
not exist out of your mind. There are electromagnetic data which can be
meaused, but science cannot interpret them, only read the values.
By chance: Science teach us there is light. Art teach us there is
light, and shadows. And darkness is not a lack of light, but another
conceptual isntrment to interpret the world. Art teach us thar light
fight with the darkness. Sceince only can measure the electromagnetic
field and the wave length of the radiation, but cannot say any thing
about what lights mean, what the pach of light move to your senses.
Art teachers are not "wrong" Art and Science are too differents
approach to understand the way we interact with the world.
Mathematics are obtused, it is not the clean field they pretend.
Mathematics talk about the triangle, the square, the circle. Figures
which not exist in the natural world. Three primaries colors are a
"rough aproach" than you must interpret. Do not limit your creation to
what science say. Science only can talk about a part of the life. Can
describe the world, not interpret it.

Ok...thank you for your reply.
As you said the 3 primaries colors are a "rough aproach" to color
mixing. However the artists' primaries (red, blue & yellow) do not
exist as pure colors and, if they did, they would be quite useless to
artists. In the approach of the 3 artists primaries - a pure yellow and
a pure blue would make black not green, a pure red and a pure blue
would also produce black and not violet.

What happens is that there is no such "red" "blue" "yellow". "Red" is
not only one color, but a "class" of color we call "red". By chance,
the magenta of CMYK is a red, so, cian, magenta and yellow is not more
than blue, red and yellow. It is "one blue", "one red", "one yellow".
