This person doesn't understand pixels lol. You picked one pixel. Pick 100 of them and average them. It's in the white spectrum with a slight shade of blue hue. If you look at it on the color wheel, it's well within white segment slightly towards the blue. When you zoom out of single pixels, it's white that you get under cool white light. It's still considered white.

As for gold, computer screens do not display gold in specular way how you see it with eyes.When you pick pixels, they will be in range of brown. Again, you don't seem to underetand pixels. And ultimately, this is suppose to be black, remember? Where's the black?

The "after" photos of a dress show dark blue with black lace details because it was not captured in bullshit lighting. Where is that on the picked pixels? Just like years ago we are once again arguing over bullshit doctored/manipulated/bad photo of a dress arguing what color it is. It's beyond stupid and I can't believe people are still this dumb to argue about colors that aren't even there. I don't care how dress actually looks, you showed me the photo of it and you're asking me how the dress looks like on the photo, not in reality. The rest is within the color picker which is mathematical representation of colors that doesn't give a shit how eyes work. And it picks very faint blue and brown (thats perceived by eyes as white and gold). Not dark blue and black.

If they were asking about actual color of the dress that you cannot see, what the fuck is the point? That's like saying, we put orange cat in fully closed box. What color is the cat? And you then claim it's not orange, it's black because there is no light inside the fully closed box so the cat is actually black. That's the level of stupid argument with this stupid ass dress.

I can also shoot a white dress to look entirely blue because I'm gonna use cool white light at 9000 fucking Kelvins and fuck up the cameras white balance to make shit look anything but its actual color. I can also take a normal photo and then just drag some sliders in photo editor and fuck up colors and then ask some bullshit question about colors and then go like "well, achtually it's not that color".

It's also funny when people argue it's not actually white because color picker says it's light blue. Firstly, color motherfucking temperature. Secondly, open color wheel and see where it's positioned. It's in the white segment mildly nudging towards blue. The part where I'm not gonna argue is perception of gradients. This isn't "this gold color is actually black bullshit", but actual science where people perceive correct colors differently. For someone a certain gradient of red is perceived as lighter or darker compared to someone else. But certainly isn't perceived as green. Or black. Or whatever other basic color.
