Well, I think it's about time that we go over why colors change when we mix them together. And all has to do with your produce department in the local grocery store. Okay, that's not entirely true. But it does have to do with why natural objects look like because that they do. If you've ever gone to the aisles of the produce departments, you know all the vibrant colors of the fruits and vegetables there. And sometimes I just wonder myself, how do we get these vibrant orange colors from oranges?

Why does a lime blue green and not some other color, these fiery red peppers have lots of brilliance to them. And you see, these cars are just as vibrant of law as a lot of the paints that we use to paint with and they are related as paints are nothing more than something we find out in nature. Write it out, write it up into a powder, then we immerse them into a fluid called a binder. And this makes all our different paints and inks and dyes. and so forth. So it all starts with these natural, organic items.

You can even have metals sometimes in there. Alright, well, it all has to do with what Adam was talking about when we understand that there's these colors in white light. That is what has to do with why things look certain colors. And that has to do with why our colors actually change color when we mix them together. So let's start at the beginning. When you have something that looks a certain color, different types of organic items have different size molecules in their molecular structure.

So these molecules have different sizes, and depending on the size of the molecules that the piece of material is made of, in this case, it's an orange. It either agrees with certain frequencies of light or disagrees depending on the size of the molecules. And that is what's making the something look a certain color and not something else. So in this case, we have a green line. And for whatever reason, the size of the molecules of this green line, I happen to agree with the green light frequencies that are hitting it right now, all the colors of the rainbow and those white light are hitting this green line. But for whatever reason, it agrees with the green frequencies, and those are being reflected back to our eye.

But it is absorbing or kind of cancelling out all the other frequencies of light or colors of light that are hitting this green line. And that's why it looks green. In this case, we have the fiery red pepper, and it's reflecting or agreeing with the red frequencies of light and it's absorbing all the other colors of the rainbow. And the orange is, as you might guess, reflecting the orange frequencies alone and absorbing or cancelling out all the other frequencies that are in the white light. So we're going to go over about maybe this five items. And that will help explain why things look a certain color in your truly understand why your colors turn into the colors as you do when you mix them together.

So just to kind of review, this is our fiery red pepper What a beautiful color. I can imagine this being some type of cadmium red paint, very deep, rich red color. And what's happening with this particular material, it's reflecting the read frequencies of light or red light waves, and it's absorbing or cancelling all the other colors. Okay, now, just a side note, this white surface that we have here it is reflecting all the cars, the wave waves, all the cars together kind of make white light so something looks white. That means it's reflecting all the cars, that those Lightwave stay white. And that's what we see we're seeing all the cars being reflected back and it combined together they make white.

So what happens with black surfaces, if something is black, that means it's absorbing or cancelling all the colors, and there is no Lightwave being reflected back, and it looks black. And if this is kind of hard to visualize or believe, think about it. If you're trying to keep cool and work clothes out in the hot sun, or you wear you wear white clothing. And the reason for that is because it's reflecting all that energy that's in light, you know, light has energy in it, all the things that we have that we use every day that have solar power, so light actually has energy in it. And if it's just bouncing off your clothing, that energy just continues on otherwise it would be absorbed in the clothes itself. That's what happens when you have black clothing, all that light energy, if it's absorbed into your black shirt, that energy has to go somewhere.

So it produces heat, and that clothing gets hot. So that's how, you know, black surfaces or materials are absorbing all that light, and white surfaces are reflecting everything. So now to understand what's really happening, when paints are mixed together and why they change the cars that they do, you have to really think and look small, you have to look really closely at something. So we'll do that. Right, this wouldn't be quite close enough. You need a really good on a very small, microscopic level, pull out your microscope.

So imagine just one paint particle almost like a grain of sand. Let's say the color red. We have kind of a little illustration here. And like this red pepper right here, for example, as we speak, this white light has all the colors of the rainbow in it. So all The different frequencies of lighter hitting this, but only the red frequencies are being reflected in this particular material. Because if it's structure absorbs and cancels all the other colors or frequencies of light, so that's what's happening with our paint particles as well.

Okay, kinda like this illustration is showing us here. So let's think about what happens when we mix paint together. Let's imagine to paint particles, let's say red and blue. Those two particles now and they're side by side floating around in the fluid. Okay, as we speak, when you mix your paint together, all the frequencies of color are hitting the red particle. But red actually absorbs all the colors of light except for red.

So red bounces off it, it's being reflected, but then it hits the guy next to him all we got blue over here, and blue on the other hand, it absorbs all the cars but blue Blue reflects off of it. But look what's happening here, they end up absorbing each other. So according to this, if this was the whole entire story, every time he makes two cars that are different together, they'd always absorb each other and make black. And actually, that's true. That's what happens. In some cases, you can make black out of two colors.

And that's what we call complimentary colors. But that's not the entire story we have to explain a little further. Paint really isn't purely reflecting one single color, there is the dominant color that is being reflected like this orange is reflecting basically, orange are frequencies but it might be also reflecting some other frequencies and smaller amounts that say, yellow, maybe some violet to maybe even some green. And that's kind of what what's happening here. Paint isn't purely reflecting only one color, but for our purposes as artists, we want to just know that there's at least one In its secondary hidden cause it's being reflected as well. For example, lizard and Crimson might reflect small amounts of other colors besides red, but it definitely reflects violet.

That's what it's known for. Ultramarine Blue definitely reflects a lot of violet as well. So this is what's happening when we mix a couple of cars together. In reality, let's say we this time we use green and violet. Okay, this is kind of what's happening here. We have ultramarine violet in definitely reflects the violet frequencies of light, but it also reflects some blue frequencies.

Now over here we have the color veridian. And that particular powder of pigment definitely reflects green. We know that because we see it's green to begin with, but also has a small amount of hidden blue that's being reflected as well. So when it came Like this, you see, one of them reflects violet in blue. The other one reflects green and blue, all the violet and the green. Because those are different, they're going to end up absorbing each other being mixed together.

But the blue is what's going to remain over after everything else is canceled out. Blue won't absorb itself. So what you end up making, or what's left over after the other to go away is blue. And kind of notice another little thing here, I kind of tricked you. This is taken to supposedly secondary colors, and we made a primary color. So there's really nothing to do with primary secondary colors.

They're all the same. The point is we want to find two colors that are different, but they share a common hidden color, common hidden color. If it's the same, that's what remains to be left over after everything cancels out. So that's what you really want to know. When you're buying your paints. You're trying to mix paints So here's one more example here.

Now we have a couple colors, we have cadmium red lights. And that color definitely obviously reflects red. But it also reflects some orange as well, maybe some other cars and small amounts. But for our purposes, it definitely has a secondary hidden color in there of orange. Now, the variety in here again, it definitely reflects green, but it also reflects a good amount of blue, like we said in the last example, wait a second here, we still have red and orange being reflected from the one in green and blue from the other, huh, none of these are the same. So they're all different.

So they're all going to cancel absorb each other. And you mix these two cars together and there's nothing left over and ends up making black. And this is what complimentary colors are. They don't complement each other at all. They actually like hate each other kind of like positive and negative and they cancel each other out and make black or some type of black But you put white in that you have some beautiful Gray's so this is how you make darker whites by using different complement scenarios or combinations and you make different types of white or grays using your complements
