Red/Blue
In my opinion, it only happened in the first chapters. I believe the authors were still undecided on the pairings, so there were a lot of ships/hints in the beginning. But come on, Red was completely head over heels with her: why else would he have bought all those items? That gold digger. ;D
Anyway, the ship was pretty much abandoned - but it returned full strength on a particularly heart touching scene in FR/LG arc. Blue was pretty much the only one who ran after him, so I'm still reticent in denying the existence of Red/Blue in the manga.
Who knows, the writers might pull a Digimon and troll the fandom, right? :D
Green/Blue
It started with them outside Celadon (I think). She was obviously appalled when he denied her advances with flat answers, and I believe that's from where her interest first slipped through. I mean, there was never a guy who really turned her down - see Red/Blue - and then, BLAM, he gives her the cold shoulder. I think that was all the motivation Blue needed, hm?
And there's also the scene in which Green falls into her arms with a mutter of "annoying woman", and Blue only smiles or cries or whatever, I can't remember. :D
Red/Yellow
Ohohoho, Red/Yellow. This is a funny one.
There was an entire arc dedicated to this pairing: Yellow searching for Red with all her might.
So. Canon.
In the GSC arc, when they finally find out she's a girl, Red was incredibly shocked. And speechless.
Canon.
First off, there was a huge load of bawling: when they were de-petrified, there were no sexy tiems with them, which, well, sucked. Needless to say, he was stoned (haha, see what I did there?) with a girl in his arms. Also he was chest-naked. Oh, authors, you. ;D
But still, you get where I'm heading at, right?
Unless Red dies in a final chapter, which I doubt, I'm pretty sure this pairing will happen. :)
Also, when Gold runs away with Red, Yellow shouts Red's name, and Crystal shouts Gold's.
Gold/Silver
Sorry fangirls, but I can't see this happening. I virtually found no clues at all, because to me, rivaling =/= sexual tension. Unless it's actually there. But to me, Gold/Silver can only happen in fanfiction. And it'll have to be a well-written one.
But you can always use the argument: rivals, look sexy together, in-game hints I'm too lazy to research and therefore apply, w/e.
(If you do have clues, you're free to tell me them, though. :D)
When Gold "died", there was extreme bawling. That reveals affection. :)
Gold/Crystal
I'm afraid I'll get biased because this is my OTP for the manga, but...
Here goes:
They meet whereas in a storm, and Gold is basically risking his life to save his. Lol, love at first sight she has boobs. For added hint effect, it's Silver the one who "rescues" her (because we all know she'd kick their asses, right? ;D). Gold then fumes and throws a fit.
It's then revealed they are complete opposites (and I hate to say it but) opposites attract. It worked with Blue/Green, right?
Also in some arc they held hands for the entire fight. I'm serious. When they're fighting against Pryce, they're holding hands. If you can't say that's a hint, I don't know what is. (Rolling of the eyes.)

Silver/Blue
I honestly find it brotherly affection, buttt~
Silver, when he firstly sees Blue's face, blushes red.
When Blue gets patted by Gold, there's the famous DON'T TOUCH HER WITH YOUR DIRTY HANDS scene. Which was a CMoA. :D
And when Silver gives her the FR/LG clothes, she blushes.
Also the rivalry between Green and Silver gives me the chills. They could be a cool triangle. ;D
