I wanted to see if I could find pen and highlighter matches for the monthly colors in the Hobonichi cousin planners, so I did A LOT of swatching and these are my choices.

I may change a few in the future if I find better matches, but this is what I owned and liked as of July 2024. Some colors are closer than others. Some look different under different lighting conditions. But what do you use? Do you color match to the Hobonichi? Let me know your thoughts and suggestions in the comments.

So what do you think? Would you ever try matching colors to your Hobonichi? I don’t think it’s necessary at all but it’s fun to play around with and see how close I could get with these options.
Major credit for most of these matches to JetPens and this super useful guide on matching supplies.
