I checked my csv file and both of the txt files Grant posted. I found 1700 lines that had your username. I ran some code to get every color you placed and still got the same results: ['000000': Black, 'unset: Undo', 'FFFFFF': White, 'F14FB4': Magenta, 'FDE111': Yellow, 'B9C3CF': Light Grey, '0334BF': Blue, 'F66E08': Rust, '777F8C': Medium Grey, '1F1E26': Dark Grey, '424651': Deep Grey, 'FF9F17': Orange, 'FFFFA5': Pastel Yellow].

If you did place red pixels (or any other shade of red/pink), it was not recorded in the log files. Maybe the pixels where lost during one of the downtimes during the event.
