  • $\begingroup$ I'm assuming it would help to know if the letters in the following locations are lowercase Ls or capital Is: O1, O2, S3, B19 $\endgroup$

  • $\begingroup$ @Matt If it's the same font as the column headers, capital i shows up with serifs, so they would be lowercase L's $\endgroup$

  • $\begingroup$ Not sure if this is relevant, but some of the boxes are 'connected' together (no black grid lines separating them). $\endgroup$

The answer is:

Somewhere in Hawaii...?

Explanation:

First, we use a vigenere cipher on the text using the key 'Aurora'. This results in:

start=t8
1_up=#5b9bd5
1_down=#ed7d31
1_right=#ffc000
1_left=#4472c4
2_up=#8497b0
2_down=#f4b084
2_right=#ffd966
2_left=#7030a0
3_up=#c00000
3_down=#ff0000
3_right=#ffff00
3_left=#00b050

The left side denotes the number of steps in a direction, while the right is a legend for those steps.

Starting at cell T8, and continuing until I couldn't anymore. I ended up with:
MjEuMzkzMDE0Oy0xNTcuODUzMzUxlA==
The last = was bolded on the grid, so I think that indicated the end.

When base64decoded, I got 21.393014;-157.853351, which on Google Maps, is somewhere in Hawaii.

Here are the colors for reference. I tried my best to match them up with the corresponding line.
