Wow really great video! I felt like I had a light bulb moment when I understood how color filters work. Thank you!

You just solved an argument about wether mixing red and green gives you yellow or mud, looks like everyone is half right here

@7:16 Cyan light passes through the cyan filter. Cyan has its own wavelength range of 485-500nm. Why is it necessary to represent cyan as a mixture of 450-485nm blue and 500-565nm green light?
@boringphysicsteacher10 ай бұрын
Hello! That is a very interesting question! Though cyan does indeed has its own wavelength, the amazing thing is that our vision perceive a mixture of blue and green light as cyan! So the cyan colour that we usually see from our screen is not of cyan wavelength, but a mixture of blue and green light (for more details on this, you can refer to my related video). Perhaps, a pure source of cyan light can be obtained by splitting sunlight through a prism.

I don't understand how red green and blue makes black.
@boringphysicsteacher2 жыл бұрын
Thank you for your question! To help you understand, first you have to imagine that paint colors are like filters. Which means that, for example, green paint only reflects and allow green light to pass through and no other light. So, if you have only red or blue light on a green paint in an enclosed room, the green paint appears to a dark (or black patch) as there is no green light to reflect to your eyes. So when you mix red, green and blue paint together, each paint will block the other color lights and very little light is reflected from the combined paint. Thus, it appears to be dark or black. Hope this helps!

then how yellow and blue when mixing colours gives us green?
@boringphysicsteacher6 ай бұрын
Hi, thank you for your question. It is likely that the shade of blue used has some elements of green within it. Thus, the common colour that is present in both yellow and "blue" is green. The shade of mixed paint green depends on the amount of green that present in the shade of blue. For example, Cyan that shown in the video (which looks like light blue) has equal amount of blue and green). A darker "blue" will has lesser green within it and will produce a darker shade of green when mixed with yellow paint. Hope it helps.

When you mix paints the first time, all combinations make black, that isn't true of paint, or artists couldn't mix colours at all. Your simulator isn't working right, red and blue paint make purple, blue and green paint makes turquoise, red and green paint makes brown. Although light is additive and paint subtractive, both use the same RGB colour wheel, and mixing any two makes something inbetween on the wheel. There isn't really a difference in the mixed output, except paint is a darker version. Red and green making brown, which is dark yellow. For example, red paint absorbs green and blue light, blue paint absorbs red and green light. Mix them together and you're absorbing red, green twice, and blue. So more red and blue light, making magenta/purple, same as if you'd mixed red and blue light.

Hi, it is because paint colors works like color filters. They only allow their own colors to be reflected and reach our eyes. So when you mixed green, red and blue paints together, no/little light gets reflected and you get a dull mess. As an analogy, it is like green, red and blue paints only wants to send their respective light representative out and prevent others from getting out. The end result is nobody gets represented as everyone is holding each other back. Mixing colors using light or shining color lights on a white surface has no such issues as the lights does not "interfere" with each other.

why was the green able to pass through the yellow?
@boringphysicsteacher Жыл бұрын
Hi! It is because when we see yellow (light), it comprises of green and red. So, in the example shown, blue and green is able to pass through cyan. However, when both light tries to pass through yellow, only green is allowed to pass through. Hope this helps!

@@boringphysicsteacher so, when two pigments are mixed into a color that disobeys the law which light mixing obeys, we can deduce that these two pigments themselves show their color by mixing multiple lights instead of showing two pure lights of two single wavelengths!

@@flavioryu5922 I am not an expert in biology, so I used ChatGPT to look up the answer. In summary, you are right! The red and green light stimulate its respective cones and our brain interprets as yellow. Reply from ChatGPT: "When green and red light mix, we perceive the color yellow due to a phenomenon called additive color mixing. This mixing of colors occurs because of how our eyes and brain interpret the combination of different wavelengths of light. In the additive color model, colors are created by adding different wavelengths of light together. Red light has a longer wavelength, while green light has a shorter wavelength. When these two colors of light are combined, they stimulate both the red-sensitive and green-sensitive cells in our eyes. The human eye contains three types of color receptors called cones, which are sensitive to different parts of the color spectrum. These cones are sensitive to short (S), medium (M), and long (L) wavelengths of light. The S cones are most sensitive to short wavelengths, which correspond to the blue part of the spectrum. The M cones are most sensitive to medium wavelengths, which correspond to the green part of the spectrum, and the L cones are most sensitive to long wavelengths, which correspond to the red part of the spectrum. When red and green light combine, they stimulate both the M cones (green-sensitive) and the L cones (red-sensitive) simultaneously. This combination of signals from the M and L cones is interpreted by our brain as the color yellow. It's important to note that this is not a physical mixing of pigments or paints (as in subtractive color mixing), but rather the combination of different wavelengths of light in the context of our visual perception. So, when green and red light are mixed together in additive color mixing, our brain processes the combined signals from the cones to create the perception of the color yellow."
