 This is this is what frustrates me so much No matter how Simple you make an explanation you get comments like this Which are just wrong? Why can't people just accept the fact that white light is all colors and black is the absence of color? Whether you're working with paints or you're working with lights Well the truth is you're always working with lights because that's what color is color is the light that reaches Your eyes, it's how your eyes take it and your brains interpret it Starting with a white canvas and painting on it is not adding color to the white I don't understand why people think this first of all most time you have a white canvas and when you paint You're not changing the color of the canvas most time the paint is over the white canvas So even if I had a black canvas and I put black red paint on there I'm not changing the color of the canvas unless you have some sort of translucent paint So in which case you have light going through the paint and it's filtering out whatever colors That are not part of that paint hitting the white and coming back out So again if you put some sort of translucent red paint on a white canvas the light will go through that paint Subtracting out it will absorb all colors, but the red it will hit the white Which will then reflect back any color that made it through in this case red and it will go back through that filter Shouldn't really be subtracting anything because it should have subtract everything the first time in a perfect world And it comes back out and you hit the red you're subtracting color if you're putting red paint on a canvas that doesn't go through You're not subtracting anything from the the canvas you're painting over the canvas and you've started off with a white paint That has pigments in it that subtract out everything but that red it's now hitting it and instead of going through it And being filtered it's bouncing off. It's absorbing the blue and the green and the red is bouncing back Never ever ever in any situation is black the presence of all colors I explained this in a previous video the video that I'm talking about I'm not going as into as much detail here because it's just frustrating when you add paints together You are subtracting colors. That's why it gets darker again if you take a white light we're talking about Additive and subtractive, but the color that the light that hits your eyes is the color whether you're adding them together or subtracting them So for example If I have three lights They're all white and I put a filter on each one a red one a blue one and a green one One on each a red one on this one a blue one on this one and a green one on this one And I project all those lights at one spot in a perfect world. We're going to get white. You're not going to get black There's no such thing as black light. I know we have black lights. Those are UV lights. They aren't really black But you have those three lights if you project a red light a green light and a blue light all at one spot You're going to get white the around the edge It's going to be kind of like a rainbow color because they're not perfectly positioned together if I take one light and I put a red filter in front of it. You're going to get a red light If I put a green it's going to get darker and I'm going to put a blue You're now getting no light through that because you've subtracted all color and now it's dark and that is what black is This is so simple, but I still get comments like this In no way does that make any sense. It doesn't matter whether you're working with pigments Color is what's hitting your eye whether it's filtering it going through or absorbing it as it's bouncing off What hits your eyes is the color another common thing I get is people going oh Well, if it's red and white light hits it and it's absorbing the green and blue then isn't it really green and blue not red No, it's the light that bounces off of it is what the color is it hits your eyes That's what color is color exists It's a concept of what your eyes and your brain interpret light waves out if you subtract away all the if you have black There are no a true black you have no light waves coming to your eyes And so therefore no color is coming to your eyes This is why when you wear a black shirt or you have asphalt outside It gets hotter than white stuff because it's absorbing that light and not reflecting it So if you have a black shirt on it's absorbing All those colors all that light energy and it gets hotter where white most of it is bouncing off as color. I Don't know why this is so hard for people to understand
