Oh, no, it’s fine, I just worry that I’ll go into a state where I’m obsessed with being “right” when in reality there is no true right answer (often because of either a lack of prerequisite information for providing proof one way or the other, or because what is “right” is merely a matter of opinion).
 
While I also don’t consider cyan an objectively warm color, when you’re talking about the color blue it’s a subjectively warm color in my mind, though still closer to being a true blue than a true green.

@Greenjack  
No, this is interesting. I try to cultivate an awareness of how perception works for deeply geeky reasons. And you’re right, that Lyra’s coat is 20° greener in [HSV] hue than her mane. Her mane though is bang on the same hue angle as #00ffff (180° in my picker), but it’s way less saturated than that triple (my head’s “monitor cyan” since forever). Whack the saturation of her coat colour up to 100% and you get #00FFAC, which is very clearly distinct on my monitor.
 
Colour perception is super relative, and it depends on contextual cues and comparisons within the image. And to me, saturation and value too, and more besides. My hats are off to anyone with a more absolute sense of hue that can’t be tricked so simply.
 
(I don’t think I could ever describe cyan as a “warm” colour, being starkly opposite pink and red. But then again I use Redshift/Night Shift/F.lux for comfort. It’s turned off now for the sake of this discussion, but I still don’t see it in the Lyra image below.)
 
(I may be geeking out too much now and I’ll stop.)

that’un’s seafoam. cyan’s more of a warm blue than a warm green. I’ll just drop this now though, since I don’t really want to risk going any further into “judgemental dick” territory.

@Greenjack, @CyanLightning  
is the “investigator” I meant. And what an adorable pic of her that is! ;)  
Although I feel it’s more that she wants to believe so hard, and got lucky that one time. Rarity is just reacting to Pinkie.
 
Twilight (who has the sense to keep silent about it) and the Monster Incursion Agencies (who would have shut her up very firmly at this point in her life) can’t distinguish between noisemakers and those with the Talent. It’s a very subjective effect until somepony opens a door to one of the really wrong places with all the teeth, hence the deep cover agent. Despite Agent Bon Bon’s best efforts, she doesn’t yet know that Pinkie is the real dea~ || BEHIND YOU! ||

@Greenjack  
Did someone say Cyan?……. Never mind. Hmmm. Rarity doesn’t look that Cyan in my laptop. And looks like when she felt her wings unfold’s monitor need some adjustment.

@when she felt her wings unfold  
If Rarity is looking cyan to you your monitor might need adjusting.

There it is again. Tilt your head just so - and it has to be the corner of your eye of course. Just a tiny glint in the air and then it’s gone. This one’s square, but they’re normally rectangular. Maybe it’s because the air’s thinner up here? Careful, careful Twilight. Don’t let on that you see them. Pinkie and that cyan unicorn definitely know something. Just keep on walking.

Or  
Twilight: can you spot the pink pony?  
Five weird seconds later  
Twilight:WONDERFUL, you found the pink pony

Which way do you think we should go, Mr human viewer?

It’s the Truman Sparkle show!
 
Twilight: “Hey! What’s this embedded in the rock?”  
Rarity: “Psst! Pinkie! Do something! She’s found a camera! She’s about to ‘Break the wall’!”

I like how she tilts her head as if she sees us. Cute

She’s getting closer D:

“Later b!%#@es”
