I discovered that I can control the local weather, depending on what color shirt and hat I wear at a given location. My home country of Flanmanistan has hired me to go back and do drought and famine relief. I never know which combination of shirt and hat will deliver which weather at a new location, because each location has a different formula. So I wear a different shirt and hat combo each day, and I fill in a grid to keep track. For example, when I wore a green shirt and purple hat, the weather became cloudy. Tomorrow, I’ll finish the grid, but I can see the pattern already. What will be the weather when I wear a blue shirt and a white hat?

Hint 1: I ask that you use decimal math.

Hint 2: My choice of weather labels is not very important. "Rain" could be changed to "Showers", "Sardines" could be changed to "Chips", etc.

Update: Hint 3: The country name (my beloved Flanmanistan) and the concept of hats and shirts are not important. Look for a way to map each color combo to one of the five weather conditions. The process is fairly simple, once you know it. Notice that Yellow and Orange produce the same weather, so something about those two colors maps the same way.

$\textbf{Weather Control Grid for Flanmanistan:}$ \begin{array}{|c|c|c|c|c|} \hline \textbf{Shirt$\downarrow$ Hat $\rightarrow$}&\textbf{Black}&\textbf{White}&\textbf{Purple}&\textbf{Gold}&\textbf{Silver} \\ \hline \textbf{Red}&Sun&Sun&Meatballs&Meatballs&Rain \\ \hline \textbf{Green}&Sardines&Sun&Cloudy&Meatballs&Rain \\ \hline \textbf{Blue}&Meatballs&?&Sardines&Sardines&Sun \\ \hline \textbf{Yellow}&Rain&Sardines&Sun&Cloudy&Meatballs \\ \hline \textbf{Orange}&Rain&Sardines&Sun&Cloudy&Meatballs \\ \hline \end{array}

  • $\begingroup$ @JonMarkPerry I wouldn't think so given the tags, but if it is then a knowledge tag would need to be added. $\endgroup$ – Jaap Scherphuis Jul 30 at 7:11

    $\begingroup$ @Conifers "Is it related to Galois finite field" Not as far as I know. I just read about Galois finite fields, and it doesn't seem to apply here. $\endgroup$ – FlanMan Jul 30 at 21:59
