glad you liked the color chart! thank you for putting this sheet together, been having a blast with it
i've also noticed the colors change, but realized that on my phone i have "dark theme", so blacks and white get inverted -- i wonder if that's feeding the confusion, since i was puzzled at first
happy to keep tinkering with the sheet! i worked on GDocs in 2010 and have been using them for my job since then, so i dabble
ps. thanks for the excitement, everyone! super fun to follow along on this thread
note: still catching up, on page 209
