Product price customization

[jabba]

Hello, i need this kind of customization:

I have a site that sells colored stones, in this way.

I have "STONE A", "STONE B", "STONE C", in the category "STONES"

Then i have:

"COLOR A", "COLOR B" in the category "YELLOWS"
"COLOR C", "COLOR D" in the category "REDS"
"COLOR E", "COLOR F" in the category "GREENS"

I have bought a 3d party component that let me build a bundle product but i need more. The price is set in this way:

STONE A = 100€
STONE B = 150€
STONE C = 200€

All colors in category YELLOWS = +10% price
All colors in category REDS = +0% price
All colors in category GREENS = -10% price

So, here are some example

STONE A + COLOR A = 100€ * 1.1 = 110€
STONE B + COLOR A = 150€ * 1.1 = 165€
STONE C + COLOR F = 200€ * 0.9 = 180€
STONE A + COLOR C = 100€ * 1 = 100€

and so on...

the last modification is that if i take 3 or more "complex items" (= stone + color) i have a 30% discount from the total

Is this possible?

Thank you very very much
