There's some randomization with the results, so the exact quantities of each fruit really needed to achieve the desired color are unknown. Likewise, since you theoretically need all of them, the order does not really matter. According to the site, if you want the color in minimal time, you would just feed everything it says and, if you don't get it, repeat the process (hopefully requiring much less the second time around). Personally, though, I just picked one at a time and fed enough of the one fruit until I got the message about growing new feathers. Takes way longer as you have to wait six hours for each shift but potentially far more efficient as far as the quantity of fruit used.
