The relationship between "lightest" and "color" does not exist without working with a specific color model. This relationship will differ between various color models because color models are not interchangeable.

Okay, let me see if I understand you correctly - Are you looking for the closest color to white which isn't white? Exactly.

Well sure its real... but George W. Bush's axis of evil lurking in this questionable video is a no no for me (haven't watched the whole thing too)

L (Lightness) being a set of values in the LaB color model I presume you are refering to CIE LaB? Which value of yellow are you refering to? I’m sure you can imagine a very dark shade of yellow which will be closer to black than to white...in some color model.

ok, I read the abstract, its about some laser printing technology where color prediction is challenging - how does this relate to what we are talking about? As to your OP - Yellow, just like any other color is a sensation which happens in the brain. Colors are managed by using models and depending on which model you use the results will vary so a statement that "Yellow is the second lightest color" doesn't make any sense unless you put it into some context.

Are you serious? The guy starts off the video with talking about a George W. Bush speech about the "Axis of Evil" (Iran, Iraq, North Korea) and proceeds seamlessly to CMB research.

This slide is just showing that a perfect set of inks in a printer (they do not exist) would behave like the mathematical model states. The next slide/graph shows that there is a discrepancy between those hypothetical, perfect inks and the ones that we have to work with in the real world.

Its difficult to read this graph without context, this graph represents that yellow behaves in a certain way in relation to other colors under some unspecified conditions. What exactly is your idea?

Which slide number? (the small pink numbering at the bottom of each slide)

Ok, these slides explain that in order to achieve an acceptable black color you need to add a separate ink to the CMY inks/toners. When you mix CMY in their maximum saturations you get sort of a black but its in fact brownish so printer manufacturers add a K ink/toner to get better results. Later the slides explain that there is a difference between the hypothetical ideal inks (defined by color models) and the real world results and the need to compensate for this by adding corrections. I have no idea where you got this from,it doesn't make any sense to me. Yellow doesn’t reflect anything, its a name for a sensation which we perceive. A certain shade of yellow can be second lightest to white in some color model you chose to work with, when you select a yellow shade which is the closest to white in that particular color model.

Anisotropies are the axis of evil? I want to learn more, please do explain.

Give me the slide title, I can't find it.

Don't worry about it. I don't see where they say anything about Yellow reflecting most of visible light on page 11 & 12.

Maybe try looking for some reliable scientific sources instead of depending on conspiracy theory lunatics who have „What is the Axis of Evil” written on a black board behind them and don’t know how to make a video with correct lipsync.

„Color is not a physical quantity which can be measured. Yet we attach it to the objects around us. Colors appear to be approximately constant to a human observer. They are an important cue in everyday life. Today, it is known that the corpus callosum plays an important role in color perception. Area V4 contains cells which seem to respond to the reflectance of an object irrespective of the wavelength composition of the light reflected by the object. What is not known is how the brain arrives at a color constant or approximately color constant descriptor. A number of theories about color perception have been put forward...” https://link.springer.com/chapter/10.1007/978-3-540-75555-5_9 And heres a half decent introduction to color management: http://cmc.printing.org/wp-content/uploads/2018/01/Hutcheson-FundamentalsOfColorMgt.pdf

Our observable universe is mostly empty space, our milky way galaxy contains more than 100 billion stars, our insignificant solar system with our average sun is on the edge of the milky way. Not only our solar system is not in any way special but our galaxy is an average, insignificant galaxy not positioned in any special way in the observable universe. There are more than a 100 bilion galaxies just in our observable universe. Considering those scales it is silly to imply that the earth is in any way special. As for the Copernican principle I suggest you drop the subject if you want to be treated like a sane person.

Nice one @Strange, I just looked up the furthest looking red dot satelite from earth and its a russian satelite launched in 1983 with a small 80cm, 160nm-350nm range telescope they did some physics experiments with. I was helping my Mom to que in lines to get toilet paper in 1983 and stuff like that was happening, wow.

How did you deduce that the earth is in a special spot in the cosmos? Give your reasoning.

No, not really. There are too many assumptions I have to make to try to make out what you’re saying due to lack of coherence in your posts. I do understand one thing though, in spite of people giving you very good and straight forward reasonining to the contrary, you keep on insisting that your faith can interweave with science on equall terms. Consider this... Physicists like all other scientists never claim they know answers to all the questions. Faith on the other hand claims that the answer to everything is God. This is a fundamental difference between religion and science - Science is full of evidence yet it is humble where Religion is full of **it yet its arogant in its fake claims to know it all.

You need to start understanding the meaning of what is being said. The discussion is pointless if you cannot understand simple posts like mine above.

Wow, this thread actually got readable for the last dozen posts.

You need to read it all again dimreepr, you don’t want to miss anything. Nobody said the path to truth will be an easy one

No worries, forget about it.

Then your faith is not faith, its trust like I suspected. Trust earned by proof like you phrase it is the very definition of science. Science is in direct contradiction to faith which is based on blind, baseless belief that pink unicorns will glaze you with rainbows next Sunday.

All the light data gathered by your sight aparatus is transported by your neural pathways to your brain. It is when the data is parsed by the brain when color occurs. So color will depend on a countless number of factors specific to a certain brain (previous experiences) You can do a cool experiment with your friend if you can get your hands on a color printer - Print a few pages with red (or any other color) color swatches which have values close to each other and compare them with a chosen red color. Do this seperately with your friend and compare results. I’ve done this excersize many times in my trainings and the results are always the same - everybody chooses different colors to match the target. Everybody sees colors differently. Literally.
