colour copying/ mixing and replacing

[seann33uk]

I currently have a problem that involves my professors lab games as some may know of. I am trying to better it by not have the colours pre made for mixing but by giving freedom to the mixing.
Currently it goes/ pick up flask of colour/ mix with other flask of colour/ get new colour (calclated direction from previous two colours)
what i want to do is / pick up flask with colour (copy RGB) mix with other flask of colour (copy RGB2)
/get new colour (weird mathamtical calculation between the two RGB collections to give a new RGB3)
if anyone understands and or better yet can help solve this problem please reply. MMF would be good but will except MMF2 or TGF2 help also.

Here's my understanding of colors:

If you are mixing light, then all you have to do is add up the colors. E.g., Mixing red and green light would be RGB(255,0,0) + RGB(0,255,0) = RGB(255,255,0).

Mixing substances such as paint is different. When you look at paint, the reason it may appear blue, for example, is because it is absorbing red and green light. And if paint appears purple, that is because it absorbs green light.

Following this, the mixing of colored substances combines their properties of absorbing light.

Suppose we want to mix together turquoise (RGB(0,255,255)) with yellow (RGB(255,255,0)). Turquoise absorbs 100% of red light, and yellow absorbs 100% of blue light. Therefore a mixture between these colors would absorb 50% of red light and 50% of blue light. Therefore, the mixed color would be RGB(128,255,128).

At least, that's my current understanding. Hope that helps.

walrus has the right idea. except that subtractive colour mixing (aka: paint) uses a different primary colour than additive mixing (aka: computer screen): RBY instead of RGB. but you know, the difference will be negligible. i would also recogmend what he said, just average each component colour value between the 1st and 2nd colours, and you'll get a convincing effect.

but if you wanted to get tricky, you could always do a wieghted ratio, taking into consideration the volumes of liquid. just a suggestion, as long as you're doing the math anyways.

okay that's useful yes and i can work with that, but now all i need to know is how do i go about collecting a colour from an active object(storing it) collecting a colour from another active object(storing that) then doing the mixing of coulrs and replacing the two previous with the new mixed colour?

Actually, I think that's a common misconception. Mixing paint, yes, you can get by on mixing red, blue, and yellow. However, the actual primary colors of paint are magenta, turqoise, and yellow. Red and blue are close enough to magenta and turqoise, so you can mix with them OK. However, I think that professional painters like to use the real primary colors to get reliable mixes.

I think I might be able to make an example for you. Hang tight.

thank you that would be great

OK here's your example.

Enjoy!
