I think it was a typo.
Either way, I don’t have the time to moderate. Someone else can.
Yeah, it was a mistake on my part. You’re right.
Want to take a turn? 
OK, fuscia, magenta, cyan, and violet.
Okay, I got one. I’ll give feedback thus: X - Right colour, right place. O - Right colour, wrong place. Exact matches take precedence over inexact and no “cell” in either code or solution is matched more than once. Hence:
Code: R G R Y
Guess: R Y Y W scores XO
(R exactly matches one of the Rs in the code, hence X. The other R in the code isn’t reported on. Y in the code inexactly matches one of the Ys in the guess, which one doesn’t matter; the other isn’t reported on)
Have at it!

I rarely get involved in the games around here. But I am genuinely baffled as to how this is fun. No snark, can someone please tell me what the enjoyment is? From what I gather, if I were to play, I pick a set of four colors from the ones in the OP, and then - you guys try to guess them? And I just tell you if you have picked one of the colors right or all but not which ones and you just have to…keep guessing?
Is that right? It sounds insanely boring, and I’ve never heard of the game before. Perhaps I’m missing something?
They’re educated guesses, not random. For every guess, and answer, there is some information revealed. The fun is in trying to correctly read those clues and make a new guess that uses what you know, and probes for more information.
X
Extended as necessary.
Also, in the real life board game, you have a limited number of guesses.
Yes, you are. Every guess and answer eliminates a proportion of the possible answers. For instance, the initial guess (blue blue blue blue) has drawn a single X, eliminating all codes that do not have exactly one blue in them. It’s revealed nothing about the other four colours, though, neither does it provide any information about which of the four possible places is actually blue. The next guess should reveal more (will reveal more, but how much more may depend on the guess).

(Aside to 'Mika: The codebreaker can deduce there is no yellow in the code: he already knew there was exactly one blue. He also knows a bit more about the location of the single blue.)
(Thank you. I am, actually, following along, to learn more about it, so I appreciate the input.)

It’s a puzzling out sort of game.
For example, look at what’s been said so far with Mal’s code.
USCDiver guessed Blue Blue Blue Blue…and got an X.
Since X = one of the colors is in the right place, we know that Blue has to be in the code somewhere and that ONE of those blues is in the right spot (very obviously, haha). But which one, is the new question?
Well, his next guess was trying the Blue out in the first spot with the guess Blue Yellow Yellow Yellow.
He got a 0 as a reply.
0 = A color is right, but in the WRONG spot. Since we know, from the other guess, that blue is somewhere in there, we therefore know that it must be the Blue that must be out of place (thus, not going in the first spot)…and that Yellow isn’t in the code at all, anywhere (otherwise we’d have gotten a “0X” which would mean the blue is in the wrong place and one of the yellows is in the right place).
So as it is, from just two guesses so far, we know:
Blue is in the code somewhere but NOT in the first spot
Yellow is not in the code at all.
It’s sort of like those logic problems you get in puzzle books.
are we still on the first game?

I’ll leave it to Idle to explain that one to the peanut gallery.
No, post #14 nailed it.
Is there an open game?
Yes, per post #37. The history so far is:
