I heard that black is the absence of color, but white is all the colors. Is this correct?

black and white are not colors they are shades. many people think that they are colors but you use black to shade your picture and or to give it a shadow and you use white to brighten you picture and or make a light source .

why is it red, green ,and blue ? the primary colors are red, YELLOW, and blue.

Light is strange, and the different primary colors are not the only difference between light and paint.For instance, when you mix paint, stirring all the primary colors together doesn't make white, it makes black.

is it hard to get a job as a color scientist?

Well, how many color scientists do you know? Color science is a pretty specialized field and if you're gonna go for it, you want to be really interested in it.

What is the unit used in the RGB model where 255 is the maximum number each value can be?

Pixel. It simply is a pixel. Each pixel is made of three different smaller pixels: red, green, and blue. The different values are the different _pixel_ values Hope that helps!

I am a fifth grader, and I am doing pretty well in the subject of color science, would it be recommended for me to continue, or should I just stop at where I'm at?

Do what you want! It doesn't matter about your grade: I started programming fourth grade! Try to acheive ahead of your level and get a place in life quickly!

i was wondering, why in this lesson does the people do 3 numbers like, 100, 12,41, when in other things that let you choose a color it has alot of numbers and letters bunched together like, #b29d60ff for a goldish color?

These are two different notations for color. The first one, with the three numbers, is RGB. It measures the amount of red, green, and blue in a color. For example, a pastel green might be RGB 134, 252, 165. The second you mentioned would be hexadecimal. Hexadecimal is another color notation. That same green I mentioned earlier would be #86fca5 in hexadecimal (or HEX) notation.

Was RGB modeled based on the Munsell system? cut into a cube? Or smooshed into a cube?

Video transcript

- [Instructor] How many different colors can you see? Feels like an endless possibility. Impossible to count them all, right? Well, if we want to represent colors digitally, we have to find a way of counting color. That is, for any given shade you can see, we need to give it a unique number or an address. Because numbers are something both humans and machines can agree on. One simple way we could do this is to give a percentage for each color value. We call this an RGB triple. For example, 100% red plus 100% green plus 100% blue is white. 0% red, 0% green, 0% blue is black. Whereas, 100% red and 100% green, but 0% blue, is yellow. We saw this in lesson one. Mathematicians love to represent things geometrically or spatially, so they came up with the idea of a color space. It's quite simple. Normally, we represent a point in three dimensional space using x, y, and z-coordinates, like this. But, instead, let's rename the axes red, green, and blue. And that gives us this color cube. The key idea is this: every point within this cube represents a specific color a projector or a computer monitor could create. So, remember all those colors you were thinking about? Well, any specific color you're looking at will always be a point in this cube. To help this sink in, we have a color cube exercise that you can play with. Give it a try.
