The primary colors.

Seggybop · Post by **Seggybop** » 2003-02-04 09:34pm

I'm tired of people saying that the primary colors for pigment (subtractive mixing) are red, yellow, blue. People believe this as fanatically as fundamentalists believe in creationism or trekkies follow Darkstar, and their level of absolute wrongness is equal.

Primary colors are supposed to have these qualities:
a. irreducible (cannot be separated into any component colors)
b. can be used to create all other colors.

Red and blue fail both of these qualifications:
Red can be produced by mixing yellow and magenta. Blue from cyan and magenta. Using only red, yellow, and blue, neither magenta or cyan can be created.

So, the real primary colors are magenta, cyan, and yellow.
I don't understand why many people are unable to accept this, but so many people deny it it causes insanity within me.

Can you post examples of these colors?

It's probably because red, yellow, and blue are the primary colors of light, and people can't understand that pigments work differently.

Its Red, Green, Blue.. I think.
Not too sure, but thats what hex code uses.

Seggy Bop youre an idiot. CMYK are SUBTRACTIVE COLORS, meaning they absorb various colors and what they dont absorb thats what they look like.

RGB are ADDITIVE colors, and when they COMBINE they make various different colors. RGB are the colors the human eye sees. When you split a rainbow apart, you find there are only three colors, RGB. CMYK are combinations there of (Cyan = green + blue, magenta = blue + red, yellow = red + green, black = independent).

In print CMYK are used because when making RGB they absorb much less then RGB. But human eyes can only see RGB. If you look at a TV screen closely you'll notice that each pixel is made of three colors: Red, Green, and Blue.

Now shut the fuck up.

He quite specifically says that he's talking about primary colors for pigments, which work on subtractive mixing.... in his very first sentence. To clarify further, take white light and the three subtractive pigments of absorb-red, absorb-green, and absorb-blue, which gives you cyan, magenta, and yellow respectively.

At least, that's what I think he's saying.

oh, nevermind then, sorry!

Yeah, it's embarrasing when that happens.

I suppose the most instructive example one could give is to simply ask the detractors to use the 'clean catridge' feature on their nearest inkjet printer. If it works anything like all the others I've seen, it will print out nice stripes of cyan, yellow, and magenta. Or, simply observe what happens when the same inkjet runs out of a particular color.

Wicked Pilot--

MAGENTA
CYAN
YELLOW

RED
GREEN
BLUE

CMY is subtractive / pigment
RGB is additive / light

For pigment,
M + C = B
M + Y = R
C + Y = G

For light
R + G = Y
R + B = M
B + G = C

Complementary colors-
R - C
G - Y
B - M

If you try to make red, yellow and blue the primary colors, besides them not even meeting the definition, you can see it makes no sense in terms of how the system is actually functioning

Ein usually has more stuff relating to railguns, and his colors are brighter.

Keep it on topic or I'll be forced to take action. Okay?

I think the problem is that we are told that in elementary school. Like how you get green by combining yellow and blue, then orange with red and yellow, and so on. You do get colors by combining them, but they aren't exactly the "base" colors.

Cyan, Magenta and Yellow is more precise, not sure exactly how long have we known this (I'm guessing since the first color print).

Red and Blue are considered "warm" and "cold" respectively, and I suppose they're easier to manage than CMY.

Colors? You want COLORS? I'll show you colors!!!!

WHEEEEEEEEEEEE!!!!

As for Railguns...

*whips out Railgun, aims at Kojikun, and squeezes the trigger*

<(BZAPP!!!)>

{SPLAT!!}

*Sn0 laughs with glee as the Depleted-Uranium Rail Slug hits flesh at Mach 8. The massive hydroshock, the flash-vaporization, the violent stripping of flesh from bone, bone immediately shattering into tiny razor-sharp shards and getting propelled throughout his body at half the slug's speed instantly severs Kojikun's body at the waist and flays it into a rapidly-expanding cloud of chunky gibs, jagged ribbons of cooked meat, and crimson salsa...*

DEFENSE!!

Grab Your Partner Do Se Do! Everybody Line Up In A Row!RAILGUN TIME!!!

IT'S PEANUT BUTTER JELLY TIME!!

Peanut Butter Jelly! Peanut Butter Jelly! Peanut Butter Jelly With a Baseball Bat!!

That's for insulting Seggybop...

Well, it would have been a valid insult if it was.
