  • Thinking about this more , you probably want this to develop a curve in your color space that represents something with constant CMYK values for your chosen light source.

    https://python-colormath.readthedocs.io/en/latest/conversions.html

    E.g. your sodium light is 100% yellow, 10ish % magenta. Any color that varies cyan from 0%-100% and black from 0%-100% should presumably not reflect any additional color information (since the source light doesn’t have any cyan and black is just giving brightness)

    I also think this means that as long as you hold Y and M constant, you can vary cyan and black for your comparison colors that will look the same. If you try to vary cyan and yellow or magenta at the same time then your effect probably won’t work.

    This is tricky because you have multiple curves in the color space that are valid when just considering a single wavelength. The reality is, your lamp emits a spectrum of light (sharp, but still has a width). There’s also the variability in perception. But I’m not sure what the “bandwidth” of our eyes is and what color resolution humans are capable of detecting.

  • Low pressure sodium lamps have a pretty sharp spectrum: https://en.wikipedia.org/wiki/Sodium-vapor_lamp

    Looking at the color spectrum, have you just tried and colors in the green to blue to purple range? I don’t think you need a Python library for this, I think you need to experiment. There’s a lot of dependence on the reflectivity of the material you’re looking at in addition to the color you see under sunlight or even indoor light with broad spectrum.

    Try blue and green and see if both look the same under the lamp.

  • See, though, this is the ignorance that stems from not knowing real life burners. The vast majority (actually none) that I know do not claim anything eco about the event. These people understand what the event is. Don’t lump every one of the 100s of thousands of those who have attended over the years with the handful of social media starlets posting bullshit online. I promise many many people at burning man hate those who post anything about the event on social media.

  • People are children and repeat what they hear. 15 years ago, I would spout the same nonsense about burning man because of what I read on digg/Reddit from the same voices you hear now. I then met a friend who convinced me to go and I had an absolute blast.

    For the vast majority of people in the US, let alone the world, attending the event is almost impossible due to cost, time, materials, etc. - it’s much easier for people that live nearby and most people within driving distance, the views of burning man will be more in line with your views - nuanced and reasonable. If you have no experience and no contact with the regular folks who attend, it’s super easy to bucket people into all these groups.

    The reasoning about waste and frivolity is total bullshit — don’t tel me your bullshit vacation to Murtle Beach is anymore eco friendly. Or your plane ride to Bangkok to become more worldly is “green”. Burning man is an event, a vacation. I went many times as a student, spending only about $2000 all in. It’s a relatively economical way to have a blast for a week.

  • Even though the brewery now classifies Negro Modelo as a Munich Dunkel, for years, I was taught it as a classic example of a Vienna Lager. Other notable examples are Sam Adams Boston Lager. I’d say more a classic German style beer than Mexican style (brought over to the country by German immigrants).

  • Take $80 billion, divide by the number of households in US with children ~ 30 million. That’s about $2700. Anyone who’s a parent knows that doesn’t go far at all in terms of education expenses. Good luck privatizing education and funding it out pocket for $3k/yr. Complete idiots.
