If 3D graphics were invented by dogs, would YBA become the standard for textures instead of RGBA?

how the fuck are we able to see the top one then

can a scifag explain why they wouldn't be able to see green if they have both blue and yellow cones? seems like some retard just made this image randomly

How the sensory input wavelengths map psycovisually inside your mind has nothing to do with the experienced color.
The brain likely evolve to experience the available input in such a way it optimize the contrast of the available input.
If you had access to the image visible to the dog it would likely not look yellow or blue at all despite the same input mapping to those colors in our brains.
It's like false color astronomy. We can map the spectrum outside the gamut of our vision to correspond to whatever part of it maximizes the visibility of what we need to see.
you will experience an intensity gradient between the two colors you can see but have no concept of the color which spectrum is depending on contribution of something unavailable to you. To us pure yellow is visible as white in both red and green, but black in the blue channel.
You design a system to force interpolate across yellow as an intermediate whenever going from green to blue you end up with artifacts in the form of non linear brightness.
More things would look equally bight and create more ambiguity as to what's what than if you just interpolated straight between the two.
Like write a shader that interpolates across yellow between blue and green and feed it the 'GB' component of a 'RGB' image and look at it's luminosity in black and white.
You'll find it washed out and having more ambiguous pixels than if you view the luminosity of something that just interpolate straight between them.
>TL:DR; the dog see's an image that maximizes the information available from it's sensory input.

yup. a good foundation in computer graphics starts with studying the physics and physiology of the human eye, which motivates a lot of things people take for granted and don't think twice about.
also, keep in mind that there are colorblind people.
