Color in light vs. color in liquid- Different or the same?

I was thinking about color recently and I realized that not only is the artistic color wheel different, but many artistic aspects dealing with color and light are almost the opposite of the RGB spectrum.

For example, in the RGB color spectrum, when all three colors hold the value of 0 then they produce black, and when they all hold a high value of 255, they produce white. However in things such as a marker, black ink is made when all the colors are combined.

This confused me then because I can't exactly wrap my head around wether this fact makes them different, or the same.

This reminded me of the experiment with a papertowel or a coffee filter, and you draw a black line on it then place the edge of the paper in water, the water absorbs, and after passing through the black carries the other colors with it, passing through the entire spectrum.

So at first I assumed these two things to be opposite, because when I think of combining colors, I think of a higher number, however now I realize that although the numerical values for black are at a value of zero, it is still a combination.

I couldn't seem to find a chromatography example with a pure black marker like I have experimented with in the past, but I am going to be doing this experiment in the next couple days to try and figure out my confusion.

Maybe they are not supposed to be related to each other even, perhaps the mixture in a black marker is simply a mixture, and shouldn't be compared with numerical RGB values....

It does make sense that they are different, due to the fact that the marker is not made up of light, but of pigments and water, however does that mean the colors of light and of what we see in markers have no relation to each other?

So is a blue color in liquid a completely different object and build compared to a blue color in light? Do they just Happen to look the same, or is there some sort of relationship between them.

Because if color is all in our minds then the color we see in light should be the same color we see in liquid (like markers etc).

Either way I'm going to try to figure it out, and maybe by researching this I'll be able to better understand the idea of the difference between the color wheels, and why they are that way.

It's definitely something to think on.

I'll post again on this subject once I've done some more research and been able to do my experiment.
