The "In a specific wavelength" ones are cheating imo
- See this rainbow? It's the sun (in a certain wavelength)
  
  Yeah, though it looks like the cyan (which would be ~500nm) is actually false color UV image, judging by the same color scale as this https://www.nasa.gov/image-detail/5-3-2024_sdo_x1pt6_flare_131/
- All but purple, blue, black and cyan seem to be real-color. I have some doubts about brown too.
  
  Which is weird that black isn't just a picture of the night sky. Has to be some fancy IR Hubble image that's been redshifted back to "true" (so doesn't that make it technically real-color again even though it's been manipulated? 🤔)
  
  Let's be honest the color "black" is just strange anyway because it is and isn't a color in a weird way.
- Meh, space might as well be B&W to our eyeballs. About every space pic we see is dialed into particular wavelengths.
  Mad props on the creativity! Be cool to see one made of all Earth photos, and much easier I would guess.
  
  While you're correct, the "specific wavelength" images still seem like cheating. Sure, purple would be pretty hard otherwise (and that purple color is a typical false color for nebulas, while the sun one is not typical for most people to see), the cyan shouldn't be hard to do. There's plenty of satalite pictures of earth with the right color, or the atmosphere. Maybe they don't want too many earth pictures, but they could ditch the white clouds for Pluto or something. White is easy. Green would be harder to replace.
- neptune is also cheating. it's not that blue and never was, it looks basically the same as uranus.
  
  It's also unrealistically bright. That far from the sun is about 900x dimmer than earth.
  
  By that argument, most of these should be black.
  
  👀
- Especially with Uranus right there for blue… i feel like Crab Nebula for purple can get a pass though.
