To the people thinking any of this is wrong or mislabeled, it *does* say "HTML color quiz", not "art book color quiz" or "what my art teacher taught me colors quiz" or any other kind of color quiz.
What you see is what you actually get if you were to place that properly within HTML and then view from within a web browser.
< html >
< body style="color:magenta" >
< /body >
< /html >
Or replace with any other color (save that as some .html file and try it out by opening it with your browser. Also remove the space after every < and before every > as I added those only to make sure this review didn't choke up or otherwise have problems posting and wouldn't mess with the page itself.
As such this game is correct. If you believe anything is wrong, go ahead and make some HTML and throw that color in there and open in a browser and see for yourself.
Also colors vary widely and most languages don't even have names for most of them except for very basic colors. English is probably the most expressive language when it comes to color names.
Even at that there's a lot of variation and a lot of it comes down to which source you are referring to.
Also color-related is the fact that the primary colors are red, green, and blue, and they are *NOT* red, yellow, and blue, as your art teacher may have incorrectly taught you. The reason they teach red, yellow, and blue (or magenta, yellow, and cyan to be technically correct) is because when you color on paper or a painting or whatever you're actually taking away color, rather than adding it.
But the way light works and what you actually see (and what your computer actually uses and thus what HTML colors actually use) is red, green, and blue as the primaries.
And yes this will cause endless argument among artists or people who fancy themselves as artists, but if you disagree you're just factually wrong.
