Is the first one green or yellow to you? (#c0ff00; It's green to us.)

Is the second one green or yellow to you? (#e0ff00; it's borderline to us, but still green.)

@IceWolf As a colourblind person I can assure you those two panels are identical.
'Red' is a conspiracy everyone is in on except me....

@wooramel Oh goodness.

We're not colorblind AFAIK and even to us, the difference is pretty subtle

they're both fairly close to Tennis Ball Green/Yellow (whether it's green or yellow depends on who you ask and is a great way to start internet fights!), but of course I don't know what exact color that is or if it's even in sRGB (probably not).

Neat that they're identical! Outta curiosity, is this the same? (straight #00ff00 green, no red channel at all)

@wooramel Funnily enough what actually prompted this was our colorblind partner not being able to tell the difference between the green and yellow modes of a "ready" button in a game (it's. bad UI.)

One of my headmates mentioned Tennis Ball Color and she was like "yes!" and so I was like "hmm that is a weird color isn't it" and posted this :3

@IceWolf S'far as I can tell... yeah.

I once started work on a 'werewolf detector' game that only colour-blind people could complete. It was fun messing with yellow text on green backgrounds and tiles with two patterns - one in subtle red and one in subtle grey.
Non-werewolves always lost the game because they could read the misleading instructions. (I'm biased toward werewolves, just so you know. Obviously werewolves are red-colourblind too....)

@wooramel Oooh that sounds awesome. :3 As a wolf myself, I bet that'd be super species-affirming if I was colorblind!
@IceWolf Heh. And devastating to discover you dont see the world as we true canines do. ;)

@wooramel Yeee. I wonder what RGB displays look like to cisspecies wolves. Like they're not just missing a cone, they ALSO presumably have different primaries, which would make things WEIRD

you'd have to custom-build a display with different liquid crystals/phosphors/whatever display tech to do the appropriate wavelengths of light

@IceWolf I think one of the visual receptors is 'yiffable/not-yiffable'
Wolves are like that.
@wooramel FuckVisionβ„’
@IceWolf The only thing that doesn't trigger those receptors is trees and rocks. And not even every tree...
