Registration-related thingies

[Muzozavr]

The first challenge question I got was "What are the three primary colors - red, blue and _". And "green" was, apparently, not the correct answer. Did the forum software seriously expect me to go old-school-artiste and type "yellow"? :/

 

Also, my mouse is faulty and apparently if you or your mouse click the "confirm" button twice in an overly rapid succession, it won't actually proceed to the next page and you won't be registered. It took me several times to understand what was probably going on.

 

Also, the "sign in with Facebook" button didn't work and gave me some weird "application doesn't exist" error.

 

Anyway, I'm here, so for me this doesn't matter anymore, just thought someone might want to take a look at this.

Red, green and blue are the primary colours for light but not for pigment or dyes. For dyes green is not correct. Some specifics will need to be added to that question, but it's definitely not an "old-school" vs "new-age" thing.

[Muzozavr]

It IS an "old-school" thing, actually, or at least a "painter-y" thing, because Cyan/Magenta/Yellow has been conclusively proven to be better for the pigments/dyes purposes, becoming the standard for color printing. They also use black for various practical reasons, but almost none of them are related to color theory. The result is known as the CMYK model. (K stands for "Key") Cyan/Magenta/Yellow simply covers more colors than Red/Blue/Yellow, period.

 

Red/Blue/Yellow is historically important, but outdated, surviving mostly due to books on art and painting using the RYB color wheel as an easy way to explain the basics of color theory. If I see "red/blue/?" I expect the last one to be green, because that's still relevant.

 

If RGB is the leading additive system, then CMY(K) is the leading subtractive system, end of. RYB is sometimes better for painters because some of the colors it covers may be more important than the CMY colors (like pure red, for example), but it isn't relevant outside of that. And don't painters normally start out with a large palette, anyway?

 

In a question like this, geared for normal users, it should be either RGB or CMY(K). RYB is old-school and painter-y.

 

Check your facts on RYB, RGB and CMYK here: http://condor.depaul.edu/sjost/gph205/paint-pigments/color-spaces.htm

 

Also, check out "Gamut" on Wikipedia in order to realize that "primary colors" aren't set in stone and are our human choices to try and cover as much of the visible spectrum as possible within a triangle. You can't cover ALL visible colors and tones with a set of 3 primary colors, either, unless your set includes imaginary colors. The image on the right really explains what's going on.

 

Sorry for unloading all this data on you, but I had to.

 

EDIT: Oh, look, Wikipedia supports me again, this time directly with the information it has on the RYB color model on THIS page. Check out the very first line:

 

"RYB (an abbreviation of red-yellow-blue) is a historical set of colors used in subtractive color mixing, and is one commonly used set of primary colors."

 

Note the word "historical".

 

Then the next line says this:

 

"It is primarily used in art and design education, particularly painting."

 

Yup. Exactly what I said, books and color wheels. The art class in your school probably used this, too.

 

Note that RYB colors definitely count as good candidates for psychological primaries, but you don't want people to have to Google that, do you?

RBG = light

RBY = paint.

Offtopic but what the heck. Most people don't even know about RGB.

First of all:

 

The question will be updated to be more specific in the near future~

 

Thank you. I genuniely appreciate this.

 

That said, I might as well continue this:

 

 

Light-based? Paint-based? Printer-based?

 

Light = additive mixing, paint/printer = subtractive mixing. So CMY applies better to both, at least in theory. There are reasons for RYB's existence, including the fact that perfect cyan/magenta paints are hard to come by, but in terms of pure color theory, CMY > RYB because it covers more colors. RYB's gamut is fairly small in comparison.

 

AFAIK, the RYB model is generally useful in color mixing, because pure cyan/magenta paints are hard to come by and unpure ones do not exactly conform to color theory. But then they don't exactly conform to RYB, either.

 

 

Unless you are indeed trying to argue that there is a modern day standard for primary colors

 

If there isn't a standard at all, the proper answer is "whatever you want". Which is, of course, incorrect, so there IS a standard.

 

If you're talking about modern standards, CMY is it. (Or RGB for light, but let's ignore this for now) Color science supports it. Even Wikipedia calls RYB "historical".

 

What I mean when I say

 

"primary colors" aren't set in stone

 

is that it's merely a choice, a theoretical model. That doesn't mean some choices/models aren't better than others.

 

There is also the practical advantage that CMY gets complementary colors better, closer to the way we actually see. For example, on a RYB color wheel, red and green are complementary (opposite) colors, but that doesn't reflect how we see. You can try a simple experiment yourself: find something intensely red (preferably on a computer, to make sure it's actually red), stare at it for about 30 seconds without blinking, then look at something else. You should see an afterimage and that afterimage will be of a complementary color. And in case of red, it will not be green, but cyan. This is from the RGB/light model (cones in our eyes and all that) but it just so happens that the CMY model works exactly the same way.

 

The "red/green, blue/yellow" opposites notion does have an underlying basis in the fact that there's no such thing as "reddish green" or "blueish yellow", the brain simply refuses to see something like that. The explanation for that is, however, more complex and totally different. They are opposites in this sense, yes, but they still aren't complementary colors, which is what the RYB model attempts to pigeonhole them as.

In America, maybe. I don't live in America, so I wouldn't know. Then again, my art class didn't teach much about color theory at all. I have encountered RYB only once, in a painting book. So even though I know about it, it's not an intuitive choice for me at all.

You've never tinkered with MS Paint's options as a kid, right?

I'm very tired at the moment and a terrible judge of my tone, actually. I sincerely hope I'm remaining reasonably civil while arguing.

Fufu, for I who pursue all evil in this board, shall not let this derailment slip off my fingers! 

 

About the issues, people can still go past mouse-thingy but the facebook problem is the real thing, not that people can't register normally--but it either needs to be fixed or removed.

[Muzozavr]

Yes, the Facebook one is strange. Thanks for re-railing the topic.

[Tay]

Thanks for reporting the registration issue and your thoughts about color theory : ). That's an old question, anyway, and needs to be replaced. Much appreciated.

 

I'm aware of the software issues and am working to fix them.
