Originally it was going to be "color" or "colors", but since different countries spell it differently and I didn't want to confuse people I decided to change it. Normally spelling wouldn't be an issue in word searches as the word list should show you the spelling, but as the whole point of this word search is that you have to figure out the secret answer I obviously can't write it down lol
The mystery word I did end up choosing isn't perfect but I think it's close enough that people will see how it relates when they find it.
I will definitely be making more of these in the future though, so I'll definitely keep in mind to pick mystery words that aren't divided by American/British English ;P
If you wanna make it more sensible to get just order the hints by rainbow order (+ the others at the bottom), so Red, Orange, Yellow, Green, Blue, Purple, Pink, Brown, Grey, Black and White.
