Here are the RGB values for the base ingredients:
Ingredient | Short | Red | Green | Blue |
Cabbage Juice | cj | 128 | 64 | 144 |
Carrots | cr | 224 | 112 | 32 |
Clay | cl | 128 | 96 | 32 |
Copper Ore | co | 64 | 192 | 192 |
Dead Tongue | dt | 112 | 64 | 64 |
Earth Light | el | 128 | 240 | 224 |
Iron Ore | io | 96 | 48 | 32 |
Lead Ore | lo | 80 | 80 | 96 |
Red Sand | rs | 144 | 16 | 24 |
Silver | si | 16 | 16 | 32 |
Toad Skin | ts | 48 | 96 | 48 |
Note that these RGB values are different from the ones in antichaos' thread, and what you will get from measuring them with a color picker. This is because the color swatch on the paint lab window is alpha-channel blended with the background of the window (the marbled tan). You need to correct for this. The best way is to take a 9x9 or 16x16 pixel averaged sample of both the swatch and the background, then apply the following formula for each color component (red, green, blue):
Real = (Measured - Background)/(250/256) + Background(which is the same as 1.024*Measured - 0.024*Background).
Some, but not all ingredients "react" with each other, and order is important.
So when you want to find your reaction number for Cabbage Juice + Dead tongue, first work out what the expected mix is: (130 + 114) / 2 for red etc... Then do the mix and sample the color. The difference from expected (so substract the expected value from the one you actually got) is your reaction value.
