The more you mix, the more it fades to gray.
Apparently the key color (in the data, blue) follows this rule: Result = avg(inputs) - 4, with some rounding in place.
The apparent rule for the non-key colors is Result = avg(inputs) + 3, again with rounding in place.
=== Non basic colors ===
We can get purple by mixing blue and red dye. What if we mix two purple dyes? If the highest color component is considered the key color and the others non-key, it will tend to balance the two high components (blue and red) with a slower fade to gray while raising the non-key color to gray level with the normal speed.
: It's more likely that any color average after mixing that is above 155 gets the -4 penalty and any color average below 155 gets the +3 bonus.
