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

I barely understand this concept now which is far better than when I found this video. 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

Great video, I was quite interested in how this worked. Thank you!

Hey Boring Physics Teacher.. thank you for this lesson... I was searching for this explanation and you clear my doubts. Love and respect form 🇮🇳

@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?

I don't understand how red green and blue makes black.

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.
