Oil mixing is a bit of an awkward art in this game, sorry about that. I've considered trying to explain the intricacies of oil alchemy in the "hints" section of the game page, but I feel like I would end up writing an essay if I did that.
Here are some pointers that may help:
- Only the dominant square matters for determining the effects of an oil. The others determine how the color shifts after mixing.
- The easiest approach is to remember what pairs well together and using exclusively those two ingredients for the mixture.
- For best results try combining ingredients that have different dominant squares, but similar colors in the squares opposite of the other's dominant color.
- The amount of oil already in the font makes a big difference. Mixing only two different ingredients forms a strong color shift with an exact average of the two. Adding a new ingredient to a 5/6 full font will only contribute 1/6 of its effect to the overall mixture.
I hope this helps you out some.
